Methacrylimide-containing polymer and resin composition containing said polymer
First Claim
1. A methacrylimide-containing polymer, which is a thermoplastic polymer comprising 2 to 100% by weight of structural units represented by the following general formula (I):
- ##STR4## wherein R represents a hydrogen atom or an aliphatic, aromatic or alicyclic hydrocarbon group having 1 to 20 carbon atoms, and 0 to 98% by weight of structural units derived from an ethylenically unsaturated monomer wherein the content of iron in the polymer is not larger than 20 ppm.

Abstract
A thermoplastic methacrylimide-containing polymer comprising 2 to 100% by weight of structural units represented by the following formula (I): ##STR1## wherein R is hydrogen or a hydrocarbon group having 1 to 20 carbon atoms, and 0 to 98% by weight of structural units derived from an ethylenically unsaturated monomer, wherein the content of iron in the polymer is not larger than 20 ppm and the difference between the maximum value and minimum value of the degree of imidization is preferably not larger than 5% by weight. This methacrylimide-containing polymer is used alone or as a blend thereof with another thermoplastic polymer.
