ABSTRACT:
A glass or mineral fiber-filled polyester resin comprising a polyetherester or poly(etherimide ester) or a blend of one or both of a polyetherester or a poly(etherimide ester) with poly(butylene terephthalate) or poly(ethylene terephthalate). The composition must not have a matrix phase of poly(butylene terephthalate) or poly(ethylene terephthalate). The fiber has substantially no adhesion for the polyester base resin. The glass or mineral fibers effectively control the coefficient of linear thermal expansion of the polymer blend. The low adhesive fiber does not result in the reduction in toughness associated with conventional reinforcing adhesive fiber (which is coated with a coupling agent for the resin).
