Abstract
1479292 Comminuted thermoplastic resins GENERAL ELECTRIC CO 21 June 1974 [18 July 1973] 27731/74 Heading C3C An injection mouldable resin is made by blending 0À10-5À0 wt. per cent of a chemical foaming agent with a thermoplastic resin, which is an aromatic polycarbonate, a polyester or a polyphenylene ether, in an extruder and comminuting the resultant extrudate, e.g. to form foamed granules. The polycarbonate may be an aromatic carbonate polymer of a dihydric phenol, e.g. bisphenyl-A, and a carbonate precursor, e.g. phosgene. The polyester may be polybutylene terephthalate. The polyphenylene ether may be in admixture with a polymer of a vinyl aromatic compound. In the Examples (I-IV) a polycarbonate was mixed in an extruder with 5-phenyltetrazole or calcium oxalate and optionally glass fibres and the extrudate was comminuted into foamed pellets which were then injection moulded; and mixtures of (V) high impact polystyrene, polyphenylene oxide and trihydrazino-s-triazine and (VI) polybutylene terephthalate, glass fibres and 5-phenyltetrazole were treated as above.
