The present invention is directed to a monomer for chain growth polymerization, in particular anionic polymerization, said monomer having the general formula (EFL) wherein: Ra is a C3-C30 alkyl, C3-C30 cycloalkyl, C6-C18 aryl or C2-C12 alkenyl group. The present invention is further directed to a process for the anionic polymerization of at least one compound (EFL) as defined above, wherein said anionic polymerization is conducted in the presence of an initiator selected from the group consisting of: alkali metal organyls; alkali metal alkoxides; alkali metal thiolate; alkali metal amides; and, compounds of an element of group 3a of the Periodic Table of the Elements. The process of anionic polymerization yields a homo- or co-polymer (p-EFL) having pendant lactone functional groups in its repeating units.
本发明涉及一种用于链增长聚合的单体,特别是阴离子聚合,所述单体具有通式(EFL),其中:Ra是C3-C30烷基,C3-C30环烷基,C6-C18芳基或C2-C12烯基基团。本发明进一步涉及一种用于上述定义的至少一种化合物(EFL)的阴离子聚合的方法,其中所述阴离子聚合在以下引发剂的存在下进行:碱金属有机基;碱金属烷氧基;碱金属硫醇酸盐;碱金属酰胺;以及元素3a族化合物。阴离子聚合的方法产生具有其重复单元中端基内酯官能团的同聚物或共聚物(p-EFL)。
