Abstract

La adición de una pequeña cantidad de un alquilsulfóxido, p. ej., DMSO, a un prepolímero rematado con isocianato proporciona una composición prepolimérica estable al almacenamiento, en la que el prepolímero está también altamente activado hacia el curado con determinados agentes de curado bloqueados tales como complejos de coordinación de metilendianilina y sal de metal. Las composiciones de prepolímero/alquilsulfóxido son curadas por dichos agentes de curado bloqueados a bajas temperaturas y/o a una velocidad acelerada en comparación con composiciones similares que carecen del alquilsulfóxido, proporcionando elastómeros de poliuretano de alto rendimiento.
