Abstract
PURPOSE: To improve the heat resistance, mechanical properties, solvent resistance, etc. of a molded article consisting of a high-melting polyamide resin, by heating it under specific conditions so that a crosslinking reaction takes place in it.
CONSTITUTION: A polyamide resin comprising preferably ≥70mol% repeating unit shown by the formula (R is 1,4-phenyl group or 1,4-cyclohexyl group; n is 10W14) as a main constitutional unit, or a resin composition obtained by blending optionally the polyamide resin with ≤70wt% nitrogen-containing aromatic resin (e.g., polyimide resin) having a glass transition temperature of preferably ≥150°C is melted and molded to give a molded article. This molded article is heat-treated in a temperature range ≥200°C and the melting point of the polyamide resin for ≥5hr, preferably ≥10hr, to give the desired molded article.
