    摘要: This invention relates to low viscosity curable polyester resin compositions and a process for the preparation thereof, 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 and (ii) a polymerizable ethylenically unsaturated monomer which serves to crosslink the unsaturated ester to a thermoset product. Fiber reinforced thermoset articles can be produced from these low viscosity curable polyester resin compositions.
