Abstract
A maleimide random copolymer contains an N-substituted compound structural unit, an unsaturated peroxycarbonate structural unit and optionally a vinyl monomer structural unit. In place of the unsaturated peroxycarbonate structural unit, an unsaturated peroxyester unit may be contained. A process for preparing a maleimide graft copolymer comprises polymerizing a mixture of an N-substituted maleimide compound and a vinyl monomer in the presence of a random vinyl copolymer containing peroxy groups with active oxygen content.
