CURABLE COMPOSITION FOR MANUFACTURING POLYURETHANE FOAM

Document Type and Number:

Japanese Patent JPS6060124

Kind Code:

A

Abstract:

A composition curable by reaction with an organic polyisocyanate to a polymer foam in which the predominant recurring polymer unit is isocyanurate, comprises a halogenated organic blowing agent; a polyester polyol mixture and a polyether polyol having an average hydroxyl functionality of at least 4 comprising the adduct of at least 4 moles of a C2-C6 alkylene oxide and an organic compound having at least 4 functional groups reactive with said alkylene oxide. The polyester polyl mixture is prepared by:… (a) transesterification, with a glycol of molecular weight from 60 to 400, of a residue remaining after dimethyl terephthalate and methyl p-toluate have been removed from the product of oxidation of p-xylene in the preparation of dimethyl terephthalate; or… (b) esterification, with an alkylene oxide selected from ethylene oxide, propylene oxide, butylene oxide, and mixtures thereof, of a carboxyl functional residue resulting from the removal of terephthalic acid from the mixture obtained by the oxidation of p-xylene in the preparation of terephthalic acid.
