LIPN聚氨酯/聚丙烯酸酯引发体系的研究

Study on the Initiating System of LIPN Polyurethane and Polyacrylate

探讨了各种引发体系对ＬＩＰＮ聚氨酯（ＰＵ）／聚丙烯酸酯（ＰＡ）合成过程的稳定性、粒子形态及单体转化率的影响。实验表明采用油溶性引发剂ＡＩＢＮ可得到粒子均一，稳定性好且单体残留量很少的乳液；其粒子形态为“翻转”

The influences of various initiating systems on the stability,morphology of latex particles of LIPN PU/PA and the conversion of monomers are studied.The experimental results show that the stabile latex with uniform particle and little residual monomers can be obtained by using AIBN initiator;The morphology of latex particles is invert coreshell structrue.
