Title:
MANUFACTURE OF POLYOL EXTENDED WITH WASTE RIM POLYURETHANE
Document Type and Number:
Japanese Patent JPS6069134
Kind Code:
A
Abstract:
Mixtures of aromatic polyols containing ester functionalities suitable for use as polyol extenders in polyurethane foams prepared by reacting dibasic acid residues with an alkylene glycol residue, the reaction product of which is reacted with recycled polyethylene terephthalate into which scrap RIM is dissolved, are described. Scrap RIM is recycled reaction injection molded polyurethane material which has been chopped or pulverized. From about 10 to 50 wt. % of the resulting modified extender polyol mixture may be scrap RIM. Surprisingly, the process is non-catalytic. These novel polyols may be blended with conventional polyols to yield excellent rigid foams, thus serving as useful polyol extenders.
