Abstract
A graft-modified polyolefin resin is provided, which is obtained by preparing a aqueous suspension containing (a1) 100 parts by weight of a polyolefin resin, (a2) 0.1 to 30 parts by weight of a mixture of 1 to 1000 parts by weight of an unsaturated glycidyl ester to 100 parts by weight of a compound having a glycidyl group as represented by a general formula (I): ##STR1## wherein Ar is an aromatic hydrocarbon group of C.sub.6 -C.sub.23 having at least one glycidyloxy group, and R is a hydrogen atom or a methyl group, (a3) 0.1 to 500 parts by weight of a vinyl monomer, and (a4) 0.001 to 10 parts by weight of a radical initiator to 100 parts by weight in total of (a2) and (a3), to thus impregnate (a1) with (a2) and (a3), and polymerizing (a2) and (a3) onto (a1). Resin compositions containig the graft-modified polyolefin resin have not only well-balanced mechanical properties, but excellent moldability.
