COMPOSITION OF POLYMER-POLIOL AND ITS USE IN THE PREPARATION OF POLYURETHANE FOAMS.

摘要

COMPOUNDS OF POLYMER POLYALCOHOL ARE PROVIDED, WHICH ARE USED FOR THE PRODUCTION OF FLEXIBLE POLYURETHANE FOAMS. POLYCOHOL POLYMER COMPOUNDS ARE COMPOSED OF (1) A HIGH-FUNCTIONAL POLYALCOHOL, (2) A SUBSIDIARY POLYALKYLENE OXIDE, HIGH CONTENT OF POLYXYETHYLENE DISPERSED. THE REAR COMPONENT IS FORMED BY "IN SITU" POLYMERIZATION OF LOW MOLECULAR WEIGHT COMPOUNDS WITHIN COMPONENTS (1) AND / OR (2) USED IN THE MANUFACTURE OF POLYMOLYHOLE POLYMER COMPOUND. POLYMAL POLYCOHOL COMPOUNDS PROVIDE STABLE AND UNINTERGABLE FOAM, WITH FREE DEVELOPMENT IN HIGH LEVELS OF WATER AND WITH CROSS LINKS AND INDICATED MARGIN, ALLOWING THE INCREASE OF DENSITY AND RELATIVE PRESSURE OF POLIALCOHOLESAL SPREADS. ALSO A PROCESS IS PROVIDED FOR ITS USE AND FOAMS AND ARTICLES PREPARED WITH THEM.
