A method is provided for salvaging organic thermoplastic values from discarded shaped organic thermoplastic substrate which has been surface treated with a protective or decorative organic coating can be salvaged and recycled. The discarded shaped organic thermoplastic substrate, such as a polycarbonate substrate can be granulated, treated with an aqueous alkaline solution which can contain a water miscible organic solvent, such as methanol and thereafter washed until neutral and dried.

Elastomeric low density foamable compositions are described which are prepared from blends comprised of a major amount of a block copolymer comprised of an alkenyl aromatic and a conjugated diene and a minor amount of one or more other thermoplastic resins. Also described are such foamable compositions wherein such blends are comprised of a major amount of a triblock copolymer of the A-B-A type and a minor amount of polystyrene resin and/or polyphenylene ether resin. Also described are processes for preparing such low density foamable compositions and articles made therefrom.

Articles having acceptable levels of impact strength and physical integrity are provided from mixed scrap plastics by a wet dispersion process. Immiscible plastic particles are locked together by a network of chopped fibers to form a useful article derived from mixed scrap plastics.

Articles from mixed scrap plastics

A thermally stable polyphenylene ether composition having long glass fibers of at least 4 mm length incorporated therein. A suitable high temperature binder such as polyethyloxazoline may be included in the composition, as well as a flame retardant additive or other filler.
