Abstract

PURPOSE: To provide titled compsn. having excellent wear resistance, Freon resistance and softening resistance, consisting of a specified polyamide-imide resin and a polyester resin having hydroxyl gp.
CONSTITUTION: (a) 1W30 equivalent % (based on the amount of total isocyanate equivalents) of an isocyanurate ring-contg. polyisocyanate having a residual isocyanate content of 10W70%, is reacted with (b) 30W80 equivalent % (base on the amount of total isocyanate equivalents) of a lactam such as ε-caprolactam and (c) an arom. diisocyanate such as tolylene diisocyanate in cresol solvent at a temp of 160W190°C for 1W3hr. Then (d) a polycarboxylic acid having acid anhydride gp. is added to the reaction mixt. in such a proportion as to give a ratio of carboxyl gp. and acid anhydride gp. to isocyanate gp. of 1.5W0.7. Further, the reaction is continued at a temp of 200W220°C for 10W20hr to produce a polyamide-imide resin (A). Then (B) 1W300wt% of a hydroxyl gp.-contg. polyester resin drived from terephthalic acid and/or isophthalic acid, is blended with the above (A).
