Abstract

1394763 Extrusion sintering SOC ITALIANA RESINE SIR SpA 11 Sept 1973 [20 Sept 1972] 42744/73 Heading B5A An acrylonitrile-butadiene-styrene copolymer powder is formed into granules of the sintered powder, by extrusion through nozzles at a temperature below the melting point of the polymer, and chopping the extrudate into the granules. The extrusion conditions comprise a powder temperature of 120 to 150‹ C. and a pressure of 300 to 500 atm., and nozzles having a diameter of 1À5 to 4 mm. The particular examples relate to acrylonitrile-butadiene-styrene copolymers prepared by graft polymerization of monomeric styrene and acrylonitrile on a polybutadiene latex by the emulsion process, and some of the examples relate to pigmentation of the granulate which is facilitated by its sintered nature. The acrylonitrile-butadienestyrene copolymer powder may be obtained from the emulsion by coagulation, separation, and drying, or alternatively by spray drying, or drying on heated rolls. The granulate is chopped by the action of stationary or rotating knives, that co-operate respectively with a rotating or stationary extrusion die of a pellet mill comprising, e.g. a rotating die and pressing rolls which frictionally heat the powder.
