## Abstract

Compounds having the formula H--A--(BA).sub.n --OH wherein n is 1-20; A is ##STR1## B is ##STR2## R.sub.1 is alkyl having 1-6 carbon atoms; R.sub.2 is an alkylene having 1-6 carbon atoms, alkenylene having 2-6 carbon atoms, cyclo-alkylene or cycloalkenylene having 5-8 carbon atoms or phenylene having 6-10 carbon atoms; a is 1-6; and b is 2-6. These compounds are useful for making polyurethanes.

a is 1-6; and
b is 2-6.

### Claim 2 (depends on 1)

Compounds according to claim 1 wherein R.sub.1 is methyl or ethyl.

### Claim 3 (depends on 1)

Compounds according to claim 1 wherein R.sub.2 is ethylene, trimethylene or tetramethylene.
