Abstract
The invention relates to improving the viscosity temperature dependence of a maturated moldable unsaturated polyester resin system, by utilizing a dual thickening system consisting of an oxide or hydroxide of magnesium or calcium and a polyisocyanate, which dual thickening system provides a greatly improved viscosity index, i.e., less viscosity decrease with increase in temperature, thereby providing substantial advantages upon being subjected to temperature increases such as are encountered in molding.
