Title:
STRUCTURE OF POLYACETAL-BASE RESIN COMPOSIITON AND PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/1992/013028
Kind Code:
A1
Abstract:
A structure of a polyacetal-base resin composition comprising a polyacetal resin and a polyolefin resin added thereto to form a network structure wherein both resins are dispersed in each other and which has good acid resistance and fusibility with a polyolefin resin and excellent mechanical properties. In the step of melt mixing the polyacetal resin (A) as a matrix with the polyolefin resin (B), a filler (C) having a surface tension at least greater than that of the component (B) at the melt mixing temperature and a mean particle diameter of 0.05 to 50 mum is added in such an amount as to satisfy the relation represented by equations (1): B/(A+B)=0.05-0.5 (by weight) and (2): C/(B+C)=0.1-0.7 (by weight).
