Claims
- 1. A blend comprising
- (a) reclaimed polyethylene terephthalate resin;
- (b) polycarbonate resin; and
- (c) graft copolymer of styrene-acrylonitrile resin on an ethylene-propylene-non-conjugated diene rubber spine, said styrene-acrylonitrile resin being present in an amount of about 5-75% by weight of the graft copolymer; and
- wherein the proportions of (a), (b) and (c) expressed in parts by weight per 100 parts of (a), (b) and (c) are as follows:
- (a) 20-90
- (b) 20-60
- (c) 20-50; and the combined parts by weight of (b) and (c) is greater than 40.
- 2. A blend comprising
- (a) reclaimed polyethylene terephthalate resin;
- (b) polycarbonate resin; and
- (c) graft copolymer of styrene-acrylonitrile resin on an ethylene-propylene-ethylidene norbornene rubber spine, said styrene-acrylonitrile resin being present in an amount of about 30-70% by weight of the graft copolymer, the graft copolymer having been worked under shearing and fluxing conditions to disperse the rubber portion of the graft within the resinous portion thereof thus forming an inverted composition in which the rubber portion is a discontinuous phase prior to blending with (a) and (b); and
- wherein the proportions of (a), (b) and (c) expressed in parts by weight per 100 parts of (a), (b) and (c) are as follows:
- (a) 20-90
- (b) 20-60
- (c) 20-50.
