PURPOSE: To obtain a modified resin which can give a molding well balanced between impact resistance and rigidity. CONSTITUTION: 100 pts.wt. metal salt of a copolymer of 70-99wt.% ethylene with 30-1wt.%α,β-unsaturated carboxylic acid, 0.1-50 pts.wt. heterocyclic- aromatic vinyl monomer containing a basic nitrogen atom as part of the aromatic ring, such as desirably 4-vinylpyridine or 2-vinylpyridine and 30-500 pts.wt. styrene monomer are subjected to aqueous suspension polymerization in the presence of a radical polymerization initiator.
