Introduction of functional groups into polyolefins has the potential of broadening their end use. An attractive method for preparing polyolefins containing functional groups is the copolymerization of the olefins with α‐olefins containing a functional group. Copolymerizations of propylene with 10‐undecen‐1‐ol, containing a hydroxyl group protected by either TIBA or TBDMSCl, 11‐chloro‐1‐undecene, 5‐bromopent‐1‐ene
将官能团引入聚烯烃具有扩大其最终用途的潜力。制备含有官能团的聚烯烃的一种有吸引力的方法是烯烃与含有官能团的α-烯烃的共聚。丙烯与10-十一碳烯-1-醇的共聚反应,其中的羟基被TIBA或TBDMSCl,11-氯-1-十一碳烯,5-溴戊-1-烯和N-烯丙基-2,2,2-三氟乙酰胺保护使用三种有机金属催化剂:茂金属rac ‐Et(Ind)2 ZrCl 2和两种新型苯甲酰胺酸盐催化剂[3‐C 5 H 4 NC(NSiCH 3)2 ] 2 TiCl2和[(米-OMe-C 6 H ^ 4 NC(NSiCH 3)2 ] 2的ZrCl 2 10-十一碳烯-1-醇的保护“在原位”与TIBA和ñ - (癸-9-烯基)-2, 2,2-三氟乙酰胺制得的共聚物具有相似的极性单体掺入百分比和分子量,分别为17%;受保护的10-十一烯-1-醇为28,900 g / mol,N为15%; N为27,100 g / mol-(癸9-烯基)-2
