Abstract

Amorphous polyolefin resin compositions having an impact resistance remarkably improved without impairing the transparency by an impact modifier which can be prepared from easily available raw materials by a general polymerization method, the compositions containing as the impact modifier a core-shell elastomer obtained by graft polymerization of a monomer mixture of an alkyl (meth)acrylate with an alkyl group having 3 to 8 carbon atoms, an alkyl (meth)acrylate with an alkyl group having 2 or less carbon atom or a vinyl cyanide compound, and an aromatic vinyl monomer in a specific ratio in the presence of a conjugated diene copolymer rubber.
