Abstract

This compound is used in the manufacture of solid expanded polyurethane. It exhibits enhanced flame resistance. The oligoester alcohol obtained has units of periodicity as follows:<IMAGE>where the value of a is 1-2; x=4-5; p=2; z=2; M.M. = 1220-1300, and where R means CH2CH2OCH2CH2;<IMAGE>The preparation method involves carrying out two-stage re-esterification of a residue from the production of dimethyl terephtalate with diethylene glycol and dimethyl ester of 1,2-di/methoxycarbonil/ethane phosphonic acid.
