Abstract

1,174,952. Moulding plastic substances. M. MAJNONI. 13 Feb., 1967 [14 Feb., 1966], No. 6865/67. Heading B5A. [Also in Division C3] Small articles e.g. buttons, jewellery which are resistant to mechanical stresses and to the action of heat and chemicals are prepared by shaping and curing an extrudable dough comprising an unsaturated polyester resin and a filler material consisting of a finely powdered cross-linked polyester resin. The dough may be extruded into a cylindrical extrudate whose cross-sectional area substantially corresponds to that of the finished article, the extrudate severed into discoidal preforms and the preforms shaped and cured by the action of heat and pressure.
