Abstract

Orthophthalic anhydride or derivatives thereof are stripped from an unsaturated polyester resin (e.g. one prepared using phthalic and maleic anhydride) which has been prepared by a polycondensation reaction carried out at atmospheric pressure or above; the resin is subjected, prior to admixture with styrene or another monomer, to a vacuum of 0-50 mm. Hg absolute, at 160-240 DEG C., for 1 second to 30 minutes. The resultant product has less tendency to crazing when immersed in water.
