Abstract

PURPOSE: To prepare the titled composition capable of giving molded items having no sink mark, by fusing and mixing a polyolefin resin composition blended with a filler containing woodflour and one blended with a filler of only inorganic substances.
CONSTITUTION: 30W70pts.wt. polyolefin and 70W30pts.wt. filler obtained by mixing woodflour having a particle size of about 100W300 mesh with an inorganic substance (e.g. calcium carbonate, talc) at a weight ratio of 1 to 1W49 are heated, fused and mixed to form composition A. On the other hand, 40W60pts.wt. polyolefin and 60W40pts.wt. inorganic substance are heated, fused and mixed to form composition B. Next, composition A and B are heated, fused and mixed at a temperature of about 200W300°C for 5W10min to obtain the titled composition.
