Abstract

PURPOSE: To prepare the titled resin having high activity, excellent radical crosslinkability, and high heat resistance, and suitable for the parts of electrical and communication equipment, by the thermal reaction of a specific unsaturated monobasic acid, an aromatic polyisocyanate, and a polyfunctional compound.
CONSTITUTION: The objective resin is prepared by reacting (A) 1 equivalent of an unsaturated monobasic acid of formula (R1 is H or 1W15C organic group; R2 is H or methyl) (e.g. acrylic acid) with (B) 1.3W10 equivalent of an aromatic polyisocyanate (e.g. tolylene diisocyanate) and (C) 0.3W9 equivalent of a polyfunctional compound having two or more active hydrogen atoms, cyclic acid anhydride groups and epoxy groups (e.g. trimellitic anhydride), if necessary in the presence of 0.001W1PHR of a polymerization inhibitor such as triethylamine, in an organic solvent such as acetone under heating at 50W180°C, pref. 80W130°C.
