- wherein R represents at least one member selected from the group consisting of an alkene group, an alkylidene group, and an oligomethylene group containing 5 or more carbon atoms, and phenylene group and naphthylene group optionally substituted with an alkyl group so that a part of the polyolefin resin (B) undergoes an in situ conversion to form the modified polyolefin resin (C) through reaction of the polyolefin resin (B) and the acid anhydride; and
- continuing the melt kneading after adding the polycarbonate resin (A) simultaneously or sequentially in an arbitrary order.
- 14. A process for producing the resin composition according to claim 1 comprising the steps of
- melt kneading the polycarbonate resin (A) and the compound (D) represented by the formula:
- HOOC--R--NH.sub.2
- wherein R represents at least one member selected from the group consisting of an alkene group, an alkylidene group, and an oligomethylene group containing 5 or more carbon atoms, and phenylene group and naphthylene group optionally substituted with an alkyl group; and
- continuing the melt kneading after adding the polyolefin resin (B), the polyolefin resin (C) that has been modified with at least one functional group selected from the group consisting of epoxy, carboxyl, and an acid anhydride groups, and a further addition of the polycarbonate resin (C) in an arbitrary order.
- 15. A resin composition according to claim 1 wherein
- the modified polyolefin resin (C) is the polyolefin resin modified with at least one functional group selected from the group consisting of carboxyl and an acid anhydride groups; and
- the resin composition has been produced through reaction of the modified polyolefin resin (C) with the compound (D) represented by the formula:
- HOOC--R--NH.sub.2
- wherein R represents at least one member selected from the group consisting of an alkene group, an alkylidene group, and an oligomethylene group containing 5 or more carbon atoms, and phenylene group and naphthylene group optionally substituted with an alkyl group, whereby a linkage represented by formula (H): ##STR5## is produced.
- 16. A resin composition according to claim 1 wherein
- the modified polyolefin resin (C) is the polyolefin resin modified with epoxy group; and
- the resin composition has been produced through reaction of the modified polyolefin resin (C) with the compound (D) represented by the formula:
- HOOC--R--NH.sub.2
- wherein R represents at least one member selected from the group consisting of an alkene group, an alkylidene group, and an oligomethylene group containing 5 or more carbon atoms, and phenylene group and naphthylene group optionally substituted with an alkyl group, whereby a linkage represented by formula (J): ##STR6## is produced.
- 17. A molded material having an improved solvent resistance comprising a molded article produced by melt molding the resin composition according to claim 1 wherein the polyolefin is dispersed in the polycarbonate in particulate form, and the particulate polyolefin present in the region from surface of the article to a depth of 20 .mu.m has an average aspect ratio (major axis/minor axis) of up to 5.
