| 摘 要： | 以乙酸乙烯酯（ＶＡＣ），苯乙烯（ＳＴ）和氯化甲基丙烯酸三甲胺乙酸（ＴＭＣ）为原料，采用元乳化剂乳液聚合法，合成出了一系列ＶＡＣ－ＳＴ－ＴＭＣ阳离子共聚物（ＰＶＳＴ）乳液，测定了乳液的稳定性和转化率，找到了合成ＰＶＳＴ的最优配方和条件。根据电镜观测，此乳液为球形粒子，粒径约为６０￣２００ｎｍ。把ＰＶＳＴ乳液加到竹浆中，测定纸张的耐折度，撕裂强度和环压强度等。当ＰＶＳＴ的用量为０．８０％时，其增强效果

| Abstract: | A series
cationic emulsion copolymers based on vinyl acetate(VAC),styrene(ST)and
trimethylaminoethyl methacrylate chloride(TMC) were synthesixzed by means of
emulsifier-free emulsion polymerization.The stability and convertibility of emulsions were
determined.The optimum condition of syntheses of copolymer was discovered.This cationic
copolymer emulsion was applied together with aluminium polychloride(APC)in paper
making.The properties of paper were the best when quantity of the applied emulsion was
0.80%. |
