Abstract:
A storage stable polyester polyol mixture is prepared by (a) digesting polyethylene terephthalate with a digesting medium comprising a polycarboxylic acid component-containing polyol derived from a digesting polycarboxylic acid component and a digesting polyol component to form a digested polyol mixture and liberate ethylene glycol from said polyethylene terephthalate, and (b) distilling from said digested polyol mixture the amount of liberated ethylene glycol sufficient for improved storage stability of the mixture. The polyester polyol mixture is useful in the preparation of cellular foam materials, particularly polyisocyanurate and polyurethane foams.

Abstract:
A storage stable polyester polyol mixture is prepared by digesting polyalkylene terephthalate, particularly polyethylene terephthalate, with a digesting medium comprising a polycarboxylic acid component-containing polyol, wherein the polycarboxylic acid component has ring units with two ##STR1## groups on adjacent or alternate ring positions, the ring unit content of the polycarboxylic acid component being sufficient for improved storage stability of the digestion product. The polyester polyol mixture is useful in the preparation of cellular foam materials, particularly polyisocyanurate and polyurethane foams.
