ELASTOMERIC LOW-DENSITY FOAMABLE COMPOSITION, ITS MANUFACTURE, AND ARTICLE MADE THEREFROM

摘要

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.
