BRANCHED POLYACETAL RESIN COMPOSITION

摘要

A polyacetal resin material which has excellent sliding properties imparted thereto and gives a molding improved in appearance, dimensional accuracy, mechanical properties, etc. The branched polyacetal composition comprises (A) 100 parts by weight of a branched polyacetal copolymer having oxymethylene groups as the main repeating units and having specific branched units, (B) 0.5 to 40 parts by weight of one or more polymers selected from the group consisting of the following polymers (B-1) and polymers (B-2) Polymers (B-1): graft or block copolymers obtained from an olefin polymer (b-1) and at least one vinyl polymer (b-2) Polymers (B-2): modified olefin polymers obtained by modifying an olefin polymer (b-3) with one or more compounds selected from the group consisting of unsaturated carboxylic acids, unsaturated carboxylic anhydrides, and derivatives of these and/or (C) 0.1 to 5 parts by weight of a lubricant.
