<p>PURPOSE:To provide a resin compsn. which has improved resistance to copper injury and heat resistance in a closed system and does not corrode nozzles, by incorporating Zn, Pb, Mg, Mn, Ba or Sn in poly-p-phenylene sulfide. CONSTITUTION:0.05-40wt% (based on the total amount of compsn.) at least one element selected from zinc, lead, magnesium, manganese, barium and tin is incorporated in a polymer composed mainly of poly-p-phenylene sulfide having at least 90mol%, pref. at least 95mol% of a repeating unit of the formula. When the content of the repeating unit is less than 90mol%, a polymer having satisfactory crystallizability can not be obtd. and the heat distortion temperature of the polymer is lowered. Thus, moldings having excellent properties can be scarcely obtd.</p> |
