    • Acrylate monomers such as methyl methacrylate, or other suitable monomers such as lactams, lactones, or acrylamides, are polymerized by reaction injection molding (RIM) utilizing a combination of organo group-4 catalysts, e.g., a neutral organo catalyst and a cationic organo catalyst. Preferably a Lewis acid is utilized which reacts with the neutral organo catalyst and forms in situ the cationic organo catalyst. Significant exotherms are rapidly generated and result in short cure times and typically in high conversions of at least 95 percent by weight of the monomer. The catalysts of the present invention give good control of tacticity and thus high Tg polymers such as syndiotactic methyl methacrylate can be produced. The use of the combination organo group-4 catalysts are well suited for reaction injection molding of finished articles wherein the neutral catalyst is fed to a mixing device in at least one stream and the cationic organo catalysts or the Lewis acid is fed in at least one or more different streams.
    • 丙烯酸酯单体如甲基丙烯酸甲酯或其它合适的单体如内酰胺,内酯或丙烯酰胺通过使用有机基团-4催化剂(例如中性有机催化剂和阳离子有机催化剂)的组合的反应注射成型(RIM)聚合 。 优选使用路易斯酸,其与中性有机催化剂反应并原位形成阳离子有机催化剂。 快速产生显着的放热,并导致短的固化时间,并且通常以至少95重量%的单体的高转化率。 本发明的催化剂可以很好地控制立构规整度,因此可以生产高Tg聚合物,如间同立构甲基丙烯酸甲酯。 使用组合有机基团4的催化剂非常适用于最终制品的反应注射成型,其中中性催化剂在至少一种料流中进料到混合装置中,阳离子有机催化剂或路易斯酸进料至少一种 或更多不同的流。
