ABSTRACT A unsaturated polyester resin composition is described that contains an epoxy resin reacted with an amine-terminated flexible polymer while dissolved in the unsaturated polyester resin and its ethylenically unsaturated crosslinking monomer. A compatible system results from the reaction which has a controllable modulus based on the amount of flexible polymer included in the resin. The resin is generally transparent if unfilled and has a higher calculated fracture energy than similar unsaturated polyester resin without modification. The unsaturated polyester resin can be filled with particulate filler or reinforced with fibrous fillers.
