METHACRYLIMIDE CONTAINING POLYMER

摘要

A methacrylimide containing polymer which is a thermoplastic polymer comprising from 2 to 100 % by weight of a structural unit represented by the general formula: where R represents a hydrogen atom or an aliphatic group, aromatic group or cycloaliphatic hydrocarbon group with 1 to 20 carbon atoms and from 0 to 98 % by weight of a structural unit derived from as ethylenic monomer, the polymer having (a) a molecular weight (Mw) of greater than 50,000 and less than 200,000 as measured by GPC, and (b) an amount of amide segments in the polymer of less than 5% by weight. The methacrylimide containing polymer has excellent transparency and heat resistance, as well as a low yellowness and aging coloration under heating. l
