METHOD OF INCREASING THE VISCOSITY OF A THERMOSET COMPOSITION AND SHAPED ARTICLES MADE FROM THIS COMPOSITION

摘要

Dissolved or dispersed thermoset resins compositions comprising at least 10% by weight of a polymerizable material and up to 90% by weight of a solvent or a dispersion medium, the molecular weight of the resins being by preference at least 500, may be thickened by the addition of a polyfunctional isocyanate and a trimerisation catalyst. The thickened compositions can be cured by a free radical catalyst and the application of heat and/or pressure. A variety of reinforced articles can be produced from the thickened compositions.
