Title:
POLYISOCYANATE COMPOUND CONTAINING LATENT TIN CATALYST AND ITS PRODUCTION
Document Type and Number:
Japanese Patent JPS62158713
Kind Code:
A
Abstract:
1. Polyisocyanate preparations consisting of : a) at least one organic polyisocyanate, b) at least one reaction product of a sulfonyl isocyanate and an organic tin catalyst present in dissolved form in the polyisocyanate preparation and, optionally, c) auxiliaries and additives known per se from polyurethane chemistry, characterized in that component b) is selected from reaction products of sulfonyl isocyanates with organic compounds containing at least one tin alkoxy, tin siloxy, distannoxane and/or tin carboxylate group : (i) the quantitative ratio between the reactants being selected so that, for every tin-oxygen bond, there is at least one isocyanatosulfonyl group of the sulfonyl isocyanate ; (ii) the reaction taking place either in the absence of the polyisocyanate component a) with subsequent mixing of the reaction product with the polyisocyanate component a) or in the polyisocyanate component a) or in part of the polyisocyanate component a) with subsequent mixing with the remainder, an auxiliary solvent optionally being used in both cases ; (iii) the reaction of compounds containing tin alkoxy and/or tin siloxy groups taking place at temperatures below 100 degrees C ; (iv) the reaction of compounds containing distannoxane groups taking place at 20 degrees to 120 degrees C with elimination of carbon dioxide ; and (v) the reaction of compounds containing tin carboxy late groups taking place above 80 degrees to 160 degrees C with elimination of carbon dioxide.
