Abstract

1479719 Foamable polyester compositions GENERAL ELECTRIC CO 21 June 1974 [2 July 1973] 27701/74 Heading C3C A foamable injection moldable thermoplastic composition comprises (a) a polyester resin or copolyester resin containing 0À5-2 wt. per cent of units derived from an aliphatic or aromatic dicarboxylic acid and/or polyol and which is a poly(ethylene terephthalate) or a poly( 1,4- butylene terephthalate) with either the above resin or 1-40 wt. per cent of a linear aliphatic polyester resin, (b) fibrous glass, a mineral and/or a synthetic silicate as filler and (c) a minor amount by weight of a foaming agent. In the Examples (1-10) poly(ethylene terephthalate) was blended with chopped glass strands and formed into pellets which were then mixed with 5-phenyltetrazole as foaming agent; blends of poly(1,4-butylene terephthalate) and poly(ethylene terephthalate) or poly(epsiloncaprolactone) were also used as the resins, and wollastonite was used as an additional filler.
