Abstract
Process for obtaining molding compositions from polyurethane precursors and cured polyester resin precursors, in particular in the form of a sheet, characterized in that in a mixture of (a) 5 to 95% by weight of the precursors of a polyurethane comprising at least one polyfunctional compound containing groups reactive with isocyanate groups and at least one polyisocyanate, the functionalities of the polyfunctional compounds and of the polyisocyanates being of the order of 2 to 5 and the functionality of the latter being greater than 2. Minus one of the polyfunctional compounds and/or at least one of the polyisocyanates, and (b) 95 to 5% by weight of the precursors of a cured polyester resin comprising at least one ethylenically unsaturated polyester and at least one ethylenically unsaturated copolymerizable with the ethylenically unsaturated groups of the polyester; optionally containing the mixture at least one monofunctional isocyanate and/or at least one monofunctional compound reactive with isocyanates; the proportions of polyfunctional compound, polyisocyanate and ethylenically unsaturated polyester being chosen so that (I) the number of moles of isocyanate-reactive groups in the polyfunctional compound plus ethylenically unsaturated polyester, when the latter contains isocyanate-reactive groups, is greater than the number of isocyanate-reactive groups. Moles of isocyanate groups of the polyisocyanate and the ratio y, ie (see formula), it is of the order of x -0.15 to x +0.15, where α defined as above or (II) the number of moles of isocyanate groups of the polyisocyanate is greater than the number of moles of isocyanate-reactive groups of the polyfunctional compound plus ethylenically unsaturated polyester, when the polyester contains isocyanate-reactive groups, and the z ratio, that is to say (see formula) is of the order of x -0.15 to x +0.15, where x is: (see graphic) The polyfunctional compound, the polyisocyanate, the ethylenically unsaturated polyester are reacted when it contains isocyanate-reactive groups, and the monofunctional isocyanate and isocyanate-reactive compound, when present, until the reaction is substantially complete, the ethylenically unsaturated monomer being virtually copolymerized unsaturated and the ethylenically unsaturated polyester.
