  • Low-profile additives for thermosetting polyester compositions
    Patent number: 5428105
    Abstract: A curable polyester molding composition incorporating an elastomeric low profile additive dispersed in voided rubbery particle form throughout the composition is used in association with a compatibilizing agent to form a molded thermoset article having very smooth, light reflective, class A surfaces and having a matrix fracture energy which is comparable to articles formed from similar or identical molding compositions which are free of low profile additives. The low profile additive is an epoxidized elastomer or block copolymer having at least one flexible elastomer block and one monovinyl aromatic block. The compatibilizing agent is a copolymer having a diene polymer backbone which is compatible with the elastomer or the flexible diene block of the low profile additive, with constituents which are compatible or reactive with the polyester being grafted or adducted onto the diene polymer backbone.
