Abstract
Stabilized polyester compositions comprise (1) an ethylenically unsaturated polyester prepared by esterifying a polyepoxide with an ethylenically unsaturated monocarboxylic acid (e.g., acrylic or methacrylic acid) in the presence of an organic phosphine catalyst (e.g., triphenylphosphine), (2) a primary or secondary amine (e.g., p,p'-dioctyldiphenylamine) and, optionally, (3) a compatible ethylenically unsaturated monomer (e.g., styrene).
