Abstract
This invention relates to an improved, matured, moldabe, thermosetting polyester resin system which includes at least two different polyester resins, one of which is faster reactive and containing a minor amount of isophthalic acid and the other of which is slower reactive and devoid of such acid, such system also including suitabe reinforcing fibers and inert filler along with an organic polyisocyanate, a metallic oxide or hydroxide, an aliphatically-unsaturated monomer, a free radical polymerization catalyst, and an internal mold release agent, the resin system being especially useful for pressure molding of precisely-formed articles having greatly improved impact resistance and flexibility.
