Abstract
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 (I): ##STR1## 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 an ethylenic monomer, in which a distribution range of an imidization radio of the polymer is less than 5%. The methacrylimide containing polymer has excellent transparency and heat resistance.
