PROCEDURE FOR THE OBTAINING OF ELASTIC POLYURETHANE MOLDED BODIES AND MAINLY COMPACT WITH IMPROVED PROPERTIES OF THE DE-MOLDING.

摘要

THE PURPOSE OF THE INVENTION IS A PROCEDURE FOR THE PREPARATION OF CLASSIC, ESSENTIALLY COMPACT MOLDED PIECES OF POLYURETHANE WITH IMPROVED DEMOLDING PROPERTIES, BY POLYISOCYANATE POLYADITION), BY TRANSFORMATION OF:) HIGH MOLECULAR WEIGHT WITH 2 reactive hydrogen atoms LEAST AND EVENTUALLY C) ALCOHOLES POLIFUNCIONALES LOW MOLECULAR WEIGHT AND / OR polyoxyalkylene WELL AS aromatic diamines SECONDARY TO YOU IN THE PRESENCE OF A D) AGENT'S INTERNAL SEPARATION OF MOLD consisting of THE COMPONENTS DETAILED IN THE INVENTION.
