ABSTRACT:
Improved flexibility properties are provided in an unsaturated polyester resin comprising the esterification product of about 85 moles of maleic anhydride and a molar equivalent of water, about 10 to about 20 moles of a fatty acid dimer or trimer, about 65 to 125 moles of dicyclopentadiene, and about 50 to about 65 mole percent, based on the total of the maleic, dimer and trimer acids, of a glycol having 2-6 carbon atoms.
