A process for reclaiming waste plastics having a paint film which includes subjecting the paint film to a hydrolysis treatment by immersing the waste plastics having a urethane paint film or an amino resin paint film in a treating liquid, or contacting the waste plastics with the vapor of a treating liquid, to decompose the paint into lower molecular weight compounds. The resulting waste plastics are then heated and kneaded to disperse the products of the hydrolysis in the waste plastics, and there is recovered a reclaimed waste plastics product having good mechanical properties.

Process for reclaiming waste plastics having a paint film

A multi-layer plastic fuel tank is constituted by at least one high-density polyethylene layer, at least one polyamide layer, and at least one modified high-density polyethylene layer made of high-density polyethylene modified with an unsaturated carboxylic acid or its derivatives, which is interposed between each high-density polyethylene layer and each polyamide layer for bonding them, the polyamide layer being made of a polyamide copolymer comprising 90-60 weight % of polyamide 6 and 10-40 weight % of polyamide 66.

Multi-layer plastic fuel tank

A polypropylene thermoplastic resin composition comprising (a) a modified crystalline polypropylene of a crystalline polypropylene comprising said modified crystalline polypropylene and (b) a modified polyamide obtained by partially or wholly grafting a polyamide with a clay mineral. A polypropylene thermoplastic resin composition comprising, in addition to the above polypropylene thermoplastic resin composition comprising the components (a) and (b), one or any combination of the following components (c), (d) and (e): (c) an ethylene-.alpha.-olefin copolymer rubber or a modified ethylene-.alpha.-olefin copolymer rubber, (d) a block copolymer between a monovinyl-substituted aromatic hydrocarbon and a conjugated diene, a hydrogenation product of said block copolymer, or a modification product of said block copolymer, and (e) an inorganic filler. The modified polyamide as the component (b), obtained by modifying a polyamide with a clay mineral has good compatibility with or good dispersibility in the component (a), i.e. the modified crystalline polypropylene or the crystalline polypropylene comprising the modified crystalline polypropylene. Therefore, the polypropylene thermoplastic resin composition comprising these components (a) and (b) has excellent heat resistance and excellent impact resistance.

Thermoplastic resin composition

A modified polyolefin-polyester graft copolymer includes (a) 10-90 parts by weight of a polyester having an intrinsic viscosity [.eta.] of 0.30-1.20 and an end carboxyl group content of 15-200 milliequivalent/kg, and (b) 90-10 parts by weight of a modified polyolefin having 0.2-5 mol % of an epoxy group or carboxyl group content and a weight-average molecular weight of 8,000-140,000. A thermoplastic resin composition includes (a) 5-95 weight % of an aromatic polycarbonate, (b) 95-5 weight % of a polyolefin, and (c) 1-30 parts by weight, per 100 parts by weight of (a)+(b), of the graft copolymer.
