The result indicated that we can get stable homopolymer and copolymer emulsion with uniform size distribution, when the ratio of sodium polyether sulfovinate modified polysiloxane to sodium lauryl sulfate was two, the quantity of the emulsifiers ranged from 6% to 8%, the quantity of initiator ranged from 0.4% to 0.8%, the stirring speed ranged from 200rpm to 250rpm, the polymerization temperature was 80 centigrade degree. As for the copolymer emulsion, the more the TRIS content in the monomers, the larger the water contact angle of their films became, namely, the surface energy of the copolymer films increased with the TRIS content in the monomers. In addition, the glass-transition temperature of the copolymers ranged from high temperature region to low temperature region with the increasing of TRIS content in the monomers.
结果表明:当乳化剂用量在6%~8%、改性乳化剂与十二烷基硫酸钠复配比为2:1、引发剂用量在0.4~0.8%、聚合温度为80℃、搅拌速度在200~250rpm时,得到的均聚物和共聚物乳液稳定,而且粒径分布均匀;对于共聚物乳液来说,随着单体中TRIS含量的增加,所得聚合物膜的水滴接触角增加,即其表面能增加:另外,随着共聚单体中TRIS含量的增加,共聚物的玻璃化转变温度从PMMA的Tg的高温区向PTRIS的Tg的低温区移动。
