Abstract

1464586 Moulds for synthetic resins RHONEPOULENC SA 6 Dec 1974 [7 Dec 1973] 52866/74 Heading B5A [Also in Division B3] A mould for articles of synthetic resin, such as rings, bushes and cog wheels, is made from a filled, insoluble, infusable resin resulting from the reaction of 1À2 to 5 moles of a bis-maleimide and 1 mole of a diprimary diamine particularly by heating between 170‹ and 350‹ C. The fillers may be glass or carbon fibres, carbon black, graphite, molybdenum disulphide, polytetrafluoroethylene or metal particles. Epoxy, phenolic and polyester resins may be moulded. The mould may be treated with a mouldrelease agent such as a linear polydimethylsiloxane or an arylsesquisiloxane or an aqueous dispersion of polytetrafluoroethylene. The mould may be made by compression moulding.
