MOISTURE-CURING POLYURETHANE COMPOSITION

PURPOSE:To prepare the titled composition which can be stored stably without decrease of the rate of cure and increase of the viscosity, by adding a polysulfide compound as a stabilizer to a polyurethane composition containing a tertiary amine or a carboxylic acid metal salt as a reaction catalyst....

Zusammenfassung:	PURPOSE:To prepare the titled composition which can be stored stably without decrease of the rate of cure and increase of the viscosity, by adding a polysulfide compound as a stabilizer to a polyurethane composition containing a tertiary amine or a carboxylic acid metal salt as a reaction catalyst. CONSTITUTION:The objective composition is prepared by compounding (A) 100pts.wt. of the reaction product of an organic compound having two or more active hydrogen atoms (e.g. polyoxypropylenetriol) and an organic polyisocyanate (e.g. diphenyl-methane-4,4'-diisocyanate), (B) (preferably =2; R and R' are group inert to isocyanate) (preferably dixylyl disulfide) as a stabilizer.
