Abstract

PURPOSE:To obtain the title resin being free of highly toxic volatile monomer and containing nonpungent compounds, by reacting 1,8-diisocyanato-4- isocyanatomethyloctane with acryl polyol at a specified ratio. CONSTITUTION:1,8-Diisocyanato-4-isocyanatomethyloctane is reacted with acryl polyol at an NCO to OH molar ratio of 0.5-2.0. In this way, the purpose polyurethane resin having a carbamide group concentration of 5X10<-4>-50X10<-4>mol per g of the reaction product and a crosslinking parameter of 150-1500 is obtained. Said trifunctional 1, 8-diisocyanato-4-isocyanatomethyloctane used is a new compound having a chemical structure of the formula. This compound has a low vapor pressure near room temperature, is not irritating to the human body and can be handled safely.
