ABSTRACT:
This invention relates to low shrinking, low viscosity curable polyester resin compositions, which compositions contain a mixture of (i) an unsaturated ester terminally modified with a reactive olefin such as dicyclopentadiene or other Diels-Alder adducts of cyclopentadiene with an olefinic or acetylenic hydrocarbon or alkylated derivative thereof, (ii) a copolymerizable ethylenically unsaturated monomer which serves to crosslink the unsaturated polyester to a thermoset product, and (iii) a thermoplastic polymer low profile additive. Cured articles prepared from these curable polyester resin compositions exhibit reduced surface roughness. Fiber reinforced thermoset articles can be produced from these curable resin compositions.
