ABSTRACT:
ABA block copolymers having saturated polyester midblocks "B" and unsaturated polyester condensation end blocks A of molecular weight from about 100 to 500 or 600 are described which increase the flexural strain to failure of unsaturated polyester or vinyl ester resins. These ABA block copolymers are generally compatible with unsaturated polyester resins and increase flexural strain by a different mechanism than used by incompatible rubbery polymers. These ABA block copolymers are compatible with the unsaturated polyester compositions and do not phase separate.
