Abstract
Novel thermoplastic molding compositions of a polycarbonate, a linear low density polyolefin, a multiphase composite interpolymer of an acrylate and a methacrylate are disclosed which have good impact strengths and reprocessability.
Claims16
A thermoplastic molding composition which comprises:
- (a) a high molecular weight polycarbonate resin;
- (b) a multiphase composite interpolymer which comprises:
- (i) a first elastomeric phase polymerized from a C.sub.1-5 alkyl acrylate;
- a crosslinking monomer;
- and a graft-linking monomer, said graft-linking monomer being a polyethylenically unsaturated monomer having a plurality of addition polymerizable reactive groups, at least one of which polymerizes at a substantially different rate of polymerization from at least one other of said reactive groups;
- and
- (ii) a final rigid thermoplastic phase polymerized at the surface of the elastomeric phase comprising a C.sub.1-5 methacrylate;
- and
- (c) a linear low density polyolefin.
