METHOD FOR MAKING RIM ELASTOMERS USING A CATALYST SYSTEM CONTAINING A POLYMERIC COMPONENT

Polymers containing tertiary amine groups, and substantially free from active hydrogen atoms, are useful catalysts for the production of reaction injection moulded (RIM) polyurethanes. These catalysts do not interfere with the curing of paints on a moulded article or interfere in the urethane networ...

Zusammenfassung:	Polymers containing tertiary amine groups, and substantially free from active hydrogen atoms, are useful catalysts for the production of reaction injection moulded (RIM) polyurethanes. These catalysts do not interfere with the curing of paints on a moulded article or interfere in the urethane network. They are advantageously employed as a solution or dispersion in one of the polyurethaneforming components. Advantageous catalysts are polymers made from monomers of the formula < IMG > wherein Y = -0- or -NH-, R1 = H or CH3, R2-R7 independently = H, CH3, or alkyl, m = 0-1, n = 0-6, and R8 and R9 independently = CH3, or alkyl, or together with the nitrogen atom to which they are attached form a N-containing heterocyclic group.
