POLYOLEFIN COMPOSITION CONTAINING HYGROSCOPIC INORGANIC FILLER, AND MOLDED BODY USING SAID POLYOLEFIN COMPOSITION

摘要

The purpose of the present invention is to provide a polyolefin composition obtained by kneading a hygroscopic inorganic filler into a polyolefin essentially without using an additive such as a dispersant or an antioxidant, said polyolefin composition having excellent moldability and good dispersibility of the hygroscopic inorganic filler. A polyolefin composition having excellent moldability and good dispersibility of anhydrous magnesium sulfate can be obtained by kneading anhydrous magnesium sulfate, which serves as a hygroscopic inorganic filler, into a polyolefin essentially without admixing an additive such as a dispersant or an antioxidant, and by setting the moisture content of the mixture to 0.1 wt% or less.
