Abstract

953,849. Injection moulding of polymers. ONDERZOEKINGSINSTITUUT RESEARCH N.V. Feb. 21, 1963 [Feb. 27, 1962], No. 6992/63. Heading B5A. In a process of injection moulding articles, e.g. combs, from polymer granules by means of an axially reciprocable screw, clogging of the screw is prevented by incorporating 1 to 0.5% by wt. of polyethylene or polypropylene (having a melt index not higher than 2) with 99 to 99.5% by wt. of a polyamide (having a relative viscosity of 2 to 3 and prepared from hexamethylene diamine and adipic acid).
