丁苯胶乳的合成研究

Study on Synthesizing Large Particle Butadine-Styrene Latex by One-step Polymerization

摘要: 以丁二烯和苯乙烯为单体、十二烷基硫醇为乳化剂,通过一步法合成了大粒径丁苯胶乳（SBR）.结果表明：乳化剂浓度、电解质浓度、固含量及单体加入方式是控制丁苯胶乳粒径大小的关键因素.通过适时补加乳化剂,选取适宜的电解质浓度、固含量及采用种子半连续加料方式有利于控制SBR粒径大小及分布.

Abstract: The influence factors on particle size of butadiene-styrene latex was studied, including emulsifier, electrolyte, initiator, TCS(total solid content).The results showed that emulsifier, electrolyte and TCS were the main influence factors on particle size
