疏水締合型聚合物(AMTA)溶液性質的研究
疏水締合型水溶性聚合物是指在聚合物親水性大分子鏈上帶有少量疏水基團的一類水溶性聚合物。在聚合物水溶液中,疏水基團之間由於憎水作用而發生聚集,使大分子鏈產生分子內和分子間締合。在臨界締合質量分數以上,形成分子間締合為主的超分子結構,增大了流體力學體積,故具有較好的增黏性。在鹽溶液中,由於小分子電解質的加入增加了溶液極性,使疏水締合作用增強,表現出明顯的抗鹽性質。 疏水締合型水溶性高分子很難合成,且不易表徵,把疏水部分連接到水溶性聚合物鏈上,一般採用膠束共聚合或者使用具有表面活性的大單體進行共聚,膠束聚合需要在體系中加入大量的表面活性劑,這就增加了後處理過程的復雜性。利用表面大單體共聚合,需要事先合成大單體,這方面的技術也有相當大的難度。作者採用丙烯酸十四酯作為疏水單體,直接用沉澱聚合法制備疏水締合型聚合物P(AM/TA)共聚物,從而使共聚反應及其產物的後處理過程較為簡單易行。並用凱達爾定氮法表徵共聚物的組成,研究共聚物的溶液性能和對苯丙乳液的增稠性。 1實驗
1.1試劑
丙烯醯胺(AM),質量分數不少於985%,根據文獻提供的方法提純;N,N-甲基甲醯胺(DMF),分析純;甲醇、氯化鈉,化學純;丙烯酸十四酯(TA),實驗室自製;苯丙乳液由福建省福州樹脂有限公司提供。 1.2P(AM/TA)共聚物的合成
稱取一定量的AM和TA單體,用DMF溶解,轉入三頸瓶中,通氮除氧。升溫至80℃,加入引發劑反應4h,過濾,產物用甲醇洗滌多次,以除去未反應的單體。40℃真空乾燥至恆重。
1.3分析測試
凱達爾定氮法測定共聚物的組成。用烏氏黏度計測定共聚物溶液特性黏度[η],測試溫度為(30±O1)℃。聚合物溶液表觀黏度用NDJ-I型旋轉黏度計測定。
2結果與討論
2.1共聚物稀溶液性質不同疏水基團摩爾分數的P(AM/TA)共聚物在蒸餾水和w(NaCl)=1.5%的溶液中的特性黏度[η]值列於表1。
聚合物的[η]正比於溶液中大分子線團的流體力學體積,因而能反應大分子線團收斂、捲曲的程度。從表1可知,隨共聚物的TA鏈節摩爾分數的增加,其水溶液的[η]值逐漸減小,在w(NaCl)=1.5%的溶液中也是持續減小。這是因為在稀溶液中,疏水基團締合以分子內締合為主,隨著TA摩爾分數的增加,分子內締合增強,導致分子鏈捲曲。在鹽溶液中,由於離子電荷的作用,使疏水鏈節分子內締合力增強,分子鏈收縮,因而[η]值也持續下降。
2.2疏水基團TA摩爾分數對聚合物溶液黏度的影響 圖1和圖2分別表示P(AM/TA)系列共聚物及PAM在蒸餾水和w(NaCl)=1.5%的溶液中表觀黏度與聚合物質量分數的關系曲線。PAM溶液黏度隨其質量分數的增加而平緩上升,而疏水共聚物溶液的質量分數為3O%~4O%時其黏度急劇增加,表明疏水基團聚集而導致分子間締合,形成了物理交聯網路。此時共聚物溶液的質量分數即是臨界締合的質量分數。如圖1所示,隨TA摩爾分數增加,共聚物溶液的黏度顯著增加。當疏水基團摩爾分數較高時,其溶液黏度隨質量分數增加的速度更快,共聚物的臨界締合質量分數降低。如圖2所示,加入Nacl溶液後,溶液表觀黏度有較大提高,如質量分數為8.O%的P(AM/TA)-1 5聚合物溶液在20℃,轉速為6r/min時,黏度達55.OmPa.s,而在水溶液中的黏度只有374mPa·s。不同TA摩爾分數的聚合物的質量分數均較其在純水中低。
Hydrophobically associating polymer P (AMTA) the nature of the study solution
Hydrophobically associating water-soluble polymer is the hydrophilic polymer with a small amount of macromolecular chain hydrophobic group of a class of water-soluble polymer. Aqueous solution in the polymer, the hydrophobic groups and between the role as a result of hydrophobic aggregation occurred, so that large molecules have a molecular chain and inter-molecular association. Associating the critical mass fraction of the above, the formation of intermolecular association based supramolecular structure, increases the volume of fluid mechanics, it has good by adhesive. In salt solution, because of the addition of small molecule electrolyte solution increased polarity, so that co-operation with enhanced hydrophobic association, shows that the nature of the salt. Hydrophobically associating water-soluble polymer-based synthesis is difficult and not easily characterized, in part to hydrophobic chains connected to the water-soluble polymer, the general use of micellar copolymerization, or the use of the large surfactant monomer to copolymerization, polymer micelles need in the system by adding a large number of surface-active agent, which, after an increase of the complexity of the process. The use of the surface monomer copolymerization, the need for prior synthesis of large monomer, this technology also has considerable difficulty. Author tetradecyl acrylate used as a hydrophobic monomer, the direct use of precipitation polymerization Preparation of hydrophobically associating polymer P (AM / TA) copolymers, so that the proct of copolymerization and post-processing is more simple and easy process. And characterization of nitrogen determination Kedar copolymer composition, study the solution properties of copolymers of styrene-acrylic emulsion and of the thickening. 1 Experimental

Check that a certain amount of monomer AM and TA, using DMF dissolved into three-neck bottle, pass oxygen nitrogen. Warming to 80 ℃, reaction by adding initiator 4h, filtering, washing the proct several times with methanol to remove unreacted monomer. 40 ℃ vacuum drying to constant weight.
1.3 Analysis and Testing
Determination of nitrogen Kedar will be the composition of copolymer. Determination of intrinsic viscosity with copolymer solution viscosity [η], the test temperature (30 ± O1) ℃. Apparent viscosity of polymer solution with NDJ-I-type rotary viscometer determination.
2 Results and Discussion
2.1 Dilute Solution Properties of Copolymers of different mole fraction of hydrophobic groups of the P (AM / TA) copolymers in distilled water, and w (NaCl) = 1.5% of the solution intrinsic viscosity [η] values listed in Table 1.
Polymer [η] is proportional to the solution of the fluid dynamics of macromolecular coil volume, which can respond to the convergence coil macromolecules, the degree of curl. We can see from Table 1, with the copolymer chain of the TA increase in mole fraction, the aqueous solution of [η] value decreases in w (NaCl) = 1.5% of the solution is continued to decrease. This is because in dilute solution, the hydrophobic group to intramolecular association based association, with the mole fraction of the increase in TA, to enhance intramolecular association, resulting in the molecular chain curly. In salt solution, because of the role of ionic charge, so that intramolecular hydrophobic chain to enter into force enhancement, molecular chain contraction, so [η] value continued to drop.
TA hydrophobic group 2.2 mole fraction of polymer solution viscosity on the impact of figures 1 and 2, respectively, P (AM / TA) series of copolymers and PAM in distilled water, and w (NaCl) = 1.5% in the apparent viscosity of the solution and the relationship between the mass fraction of polymer curve. PAM solution viscosity with the increase of mass fraction of gentle rise, and the hydrophobic copolymer solution for the mass fraction of 3O% ~ 4O%, when a sharp increase in viscosity, indicating that aggregation of hydrophobic groups and lead to intermolecular association, forming a physical crosslinking網路. At this point the mass fraction of copolymer solution that is the critical mass fraction of the association. As shown in Figure 1, with the mole fraction of TA increased, the viscosity of copolymer solution increased significantly. When the mole fraction of hydrophobic groups is high, the solution viscosity increases with the mass fraction of the faster, the critical aggregation copolymer mass fraction lower. As shown in Figure 2, by adding Nacl solution, the solution has greatly enhanced apparent viscosity, such as the mass fraction of 8.O% for the P (AM / TA) -1 5 polymer solution at 20 ℃, rotation speed 6r/min , the viscosity of 55.OmPa.s, and viscosity in aqueous solution only 374mPa s. TA different mole fraction of the mass fraction of polymer in water were low.

㈧ 對環境化學比較重要的外文期刊有哪些
不是很了解環境化學,我實驗技術很渣,我聽過和環化有關的口碑比較好的期刊,EST(Environmental science and Technology)算一個,這期刊非常重視新意,不過這兩年好像有點下降的趨勢,EST涉略比較廣,幾乎各個領域都有所囊括。Chemistry And Physics (ACP) 算是大氣領域的頂級期刊了,水領域我們這里比較認可WR (Water Research),土壤領域Soil Biology & Biochemistry(SBB)應該算是公認的比較好的期刊了。有害的環境廢物可以考慮JHM (Journal of Hazardous Materials),一區TOP期刊,算是不錯的了,雖然有人感覺有點水,但是影響因子擺在那了,而且還是TOP。Bioresource Technology (BT), 和 Environmental Pollution (EP)也算是影響比較高的。最後Chemosphere 我們這里也是比較認可的,應該是2區TOP期刊。
