Abstract

PURPOSE: To prepare the titled isophthalate-type resin having excellent water resistance, chemical resistance, mechanical properties, etc., economically, in a short time, by reacting an oligoester of isophthalic acid and propylene oxide with an unsaturated dibasic acid (anhydride).
CONSTITUTION: An oligoester of formula (n and m are 0, 1, 2, 3,...) is prepared by reacting 1mol of isophthalic acid with 1.2W3.0mol of propylene oxide in the presence of a tetraalkylammonium salt catalyst[e.g. (C2H5)4NCl; its amount is 0.001W0.5wt% of isophthalic acid]using an oigoester obtained by the reaction of isophthalic acid with propylene oxide or propylene glycol as a reaction medium. The obtained oligoester is heated at 180W280°C to remove the volatile component, condensed with an unsaturated dibasic acid (anhydride) (e.g. maleic anhydride), and compounded with a polymerization inhibitor and a vinyl monomer (e.g. styrene) to obtain the objective resin.
