IMPROVED SINGLE-COMPONENT POLYURETHANE SYSTEM STABLE DURING STORAGE Russian patent published in 2011 - IPC C08G18/10 C08G18/74 C08G18/32 

FIELD: chemistry.

SUBSTANCE: invention relates to a fluid polyurethane composition which is stable during storage and which is used to produce polyurethane elastomeric products, including: (a) one or more polyurethane prepolymers with terminal isocyanate groups obtained from one or more diisocyanates and/or triisocyanates containing a hydrocarbon ring, and one or more polyols; (b) one or more methylene dianiline complexes of metal salts; and (c) one or more organic acid halides, having one or more acid halide groups, where one or more organic acid halides are present in an amount where organic acid halide groups are present in minimal concentration equal to approximately 100 ppm in terms of the weight of the polyurethane prepolymer. The invention also relates to a method of storing the curable polyurethane composition and polymer elastomeric product obtained using a method which involves heating the polyurethane composition which is stable during storage.

EFFECT: obtaining a polyurethane composition which is curable until obtaining an elastomeric polyurethane product at the corresponding curing temperature while also demonstrating stability and fluidity during storage at relatively high temperatures.
