Abstract

1447304 Polyolefin compositions NISSAN KAGAKU KOGYO KK 24 April 1974 [25 April 1973] 17930/74 Heading C3P Granular crystalline polyolefin compositions for moulding are prepared by a process wherein crystalline polyolefin resin powder and/or grain is mixed with finely powdered inorganic filler in amount of 10 to 80 weight per cent of the composition and is heated from a temperature below the melting point of the resin under agitation sufficient to raise the temperature of the mixture by friction to a temperature within the range from the melting point of the resin to the decomposing point of the resin thereby yielding a weak coagulation of resin composition, until a coagulated block product begins to be produced and the product is cooled to a temperature below the melting point of the resin. The process may be effected in a tank provided with a rotating vane which may be operated initially at high speed, and then at lower speed when coagulation has begun. The resin may be a polypropylene or polyethylene. The filler may be talc, kaolin, clay, calcium carbonate, magnesium carbonate, barium sulphate, calcium sulphate, carbon black, titanium dioxide, silica, alumina, lead oxide or zinc oxide; and the compositions may also contain stabilizers, lubricants, modifying agents and colorants. Examples describe the preparation of compositions comprising polyethylene and (1 and 2) calcium carbonate and (3) talc; and polypropylene and (4) barium sulphate.
