摘要：A monofunctional alcohol or acid is used to chain stop a condensation reaction for preparing a low molecular weight unsaturated polyester resin. The monofunctional acid removes terminal hydroxy groups and replaces them with hydrocarbon groups. The monofunctional alcohol removes terminal carboxy groups and replaces them with hydrocarbon groups. The resulting polyester resins have improved hydrolytic stability. These chain stopped unsaturated polyester resins can be further modified with hydroxy acrylates, other hydroxy terminated polyesters, and diisocyanates to produce resins with excellent water resistance and physical properties for various applications, such as marble/onyx resins, sheet molding compounds, bulk molding compounds and resin transfer molding resins, gel coats, and bowling ball resins.
