Abstract
Replacement of one-third to two-thirds of the short chain diols in a polyisocyanate/polymeric polyol/short chain diol molding composition with a hydroxyalkyl-melamine provides shaped articles of increased high temperature stiffness and reduced heat sag. The hydroxyalkylmelamine is strongly catalytic for the isocyanatepolyol reaction.
