New regulator compounds for a novel polymerization process for vinyl monomers, which yields polymers with improved control over composition and nearly full to full conservation of architectural integrity up to high conversion. The regulator compounds are defined by according to anyone of the Formulas 1A, 1B, 1C, 1D, 1E, 1F, 1G, 1H and 1I:
wherein R1 stands for an optionally substituted secondary or tertiary alkyl or secondary or tertiary aralkyl; Z1 stands for —CN or a carboxylic acid ester of formula C(O)OR21; Z2 may be chosen from the group of —CN, carboxylic acid, salts of carboxylic acids, carboxylic acid ester, carboxylic acid amides, (hetero)aryl, alkenyl and halogen; R2, R3, R4 and R5 are each independently chosen from the group of H, alkyl, aralkyl, (hetero)aryl, —CN and carboxylic acid ester of formula C(O)OR22; R7 stands for a primary alkyl or primary aralkyl, —CN or hydrogen; Y stands for a bridging group and n is 2, 3, 4, 5 or 6; in case R1 stands for tertiary alkyl or tertiary aralkyl, R6 stands for a primary alkyl or primary aralkyl, —CN or a carboxylic acid ester of formula C(O)OR26; in case R1 stands for a secondary alkyl or secondary aralkyl, R6 stands for a primary or secondary alkyl or primary or secondary aralkyl, —CN, a carboxylic acid ester of formula C(O)OR26 or a phosphonic acid ester of formula P(O)(OR27)2, a (hetero)aryl or an alkenyl; R21, R22, R26 and R27 each independently stand for alkyl or aralkyl having from 1-30 carbon atoms, optionally containing heteroatoms.
用于乙烯基单体新型聚合工艺的新型调节剂化合物,该工艺生产的聚合物可改善对成分的控制,并在高转化率条件下几乎完全保持结构的完整性。这些调节剂化合物是根据公式 1A、1B、1C、1D、1E、1F、1G、1H 和 1I 中的任何一个公式定义的:
其中 R1 代表任选取代的仲或叔烷基或仲或叔烷基;Z1 代表-CN 或式 C(O)OR21 的羧酸酯;Z2 可选自-CN、羧酸、羧酸盐、羧酸酯、羧酸酰胺、(杂)芳基、烯基和卤素;R2、R3、R4 和 R5 各自独立地选自 H、烷基、芳基、(杂)芳基、-CN 和式 C(O)OR22 的羧酸酯组;R7 代表伯烷基或伯芳基、-CN 或氢;如果 R1 代表叔烷基或叔芳烷基,R6 代表伯烷基或伯芳烷基、-CN 或式 C(O)OR26 的羧酸酯;R1代表仲烷基或仲烷基,R6代表伯烷基或仲烷基或伯烷基或仲烷基、-CN、式C(O)OR26的羧酸酯或式P(O)(OR27)2的膦酸酯、(杂)芳基或烯基;R21、R22、R26和R27各自独立地代表具有1-30个碳原子的烷基或芳烷基,可选择含有杂原子。
