ABSTRACT:
Disclosed is a polyoxyalkylene derivative which is useful for a carboxyl group-containing polyurethane resin, can easily introduce a carboxyl group into a polyurethane resin skeleton, and has a low melting point or is in a liquid state at normal temperature. The polyoxyalkylene derivative is represented by formula (I): ##STR1## wherein R.sub.1 represents a hydrogen atom or an alkyl group having from 1 to 3 carbon atoms; R.sub.2 represents an alkylene group having from 1 to 6 carbon atoms or an arylene group having from 6 to 8 carbon atoms; A represents an alkylene group having from 4 to 7 carbon atoms; B represents an alkylene group having from 2 to 6 carbon atoms; l represents from 0 to 2; m represents from 0.1 to 35; n represents from 0.1 to 50; and 0.5<(m+n)<50.
