Document Type and Number:
Japanese Patent JPH0455413
Kind Code:
A
Abstract:
PURPOSE:To obtain a surface modifier providing a crystalline resin with surface glass and beautiful appearance, comprising a maleimide-based copolymer containing a maleimide derivative, an aromatic vinyl compound and a vinyl- based monomer copolymerizable with said derivative and said compound, and having a specific molecular weight. CONSTITUTION:The objective modifier comprising a maleimide-based copolymer containing (A) 1-99 wt.% maleimide derivative (e.g. maleimide or N- methylmaleimide), (B) 1-99 wt.% aromatic vinyl compound (e.g. styrene or vinylnaphthalene) and (C) <=50 wt.%, perferably 1-30 wt.% vinyl-based monomer [e.g. acrylonitrile or methyl (meth)acrylate]copolymerizable with the derivative (A) and the compound (B), and having 1,000-500,000 weight-average molecular weight.
