Abstract
An unsaturated polyester resin composition is described that contains an amine-terminated flexible polymer that can react with the unsaturation in the polyester. A compatible system results that has higher fracture toughness. The preferred amine-terminated flexible polymer is an amine-terminated poly(butadiene-co-acrylonitrile). The resin composition can be extended with fillers and reinforced with fibers. In these applications, the resin is known as a matrix resin.
