Abstract
A polyacetal composite according to the invention includes a polymer unit (A) composed of a polyacetal resin, and a polymer unit (B) composed of a thermoplastic resin or elastomer having an acidic group, and the polymer unit (A) and the polymer unit (B) directly adhere to each other. The acidic group includes, for example, a carboxyl group and a carboxylic anhydride group. The thermoplastic resin or elastomer having an acidic group includes a comonomer having at least one selected from among acrylic acid, methacrylic acid, fumaric acid, maleic acid, maleic anhydride, and itaconic acid as a comonomer, and typical examples thereof include, for example, acid-modified polystyrene and acid-modified NBR (acid-modified nitrile rubber). In this polyacetal composite, the polyacetal resin and another polymeric material are firmly fixed with each other.
