Functionalized α-angelica lactone monomers and polymers obtained therefrom

Abstract

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 C1-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.
