Molded polysulfide ketone article

Abstract

Abstract PURPOSE:The titled molded article, consisting of a polysulfide ketone having a specific structure and a density of polymer alone within a specific range, improved heat resistance at high temperatures and mechanical characteristics and improved productivity due to the constituent polymer having a simple structure. CONSTITUTION:A molded article obtained by using a polysulfide ketone, consisting of units expressed by the formula, and having 1.28-1.32g/cc density. The above-mentioned polymer is preferably obtained by sulfiding a 4,4'-dihalobenzophenone, e.g. 4,4'-dichlorobenzophenone, with sodium sulfide in an organic polar solvent, e.g. dimethylacetamide. The heat treatment for producing the above- mentioned molded article is preferably carried out at 180-310 deg.C for 10sec-1hr.
