Abstract
Alkoxylated polyester polyols useful in the manufacture of polyurethanes are disclosed.
Claims28
Alkoxylated polyester polyols formed by reacting at least one non-gelled polyester polyol of the formula:
- R--O--A--H].sub.p
- where
- R is a polyol residue;
- p is an integer from 2 to 6;
- and,
- A may be the same or different and is selected from the group consisting of A.sub.1, A.sub.2 and A.sub.3 and combinations of A.sub.1, A.sub.2 and A.sub.3, where ##STR12## where m, n, q, r, .alpha., .beta. and .gamma. are integers and where
- m>3
- n.gtoreq.0 and
- m+n is from 11 to 19
- q>3
- r.gtoreq.0
- s.gtoreq.0 and
- q+r+s is from 10 to 18
- .alpha. is from 0 to 10
- .beta. is from 0 to 10 and
- .gamma. is from 1 to 10, except that all .alpha.'s, .beta.'s and .gamma.'s in any given compound are not all zero;
- with at least one alkylene oxide in a ratio of moles of alkylene oxide per equivalents of hydroxyl in the polyester polyol from about 0.5:1 to 5:1.

Alkoxylated polyester polyols formed by reacting at least one non-gelled polyester polyol of the formula:
- ##STR13## where R.sup.1 is a polyol residue;
- p is an integer from 2 to 6;
- .alpha. is an integer from 0 to 10 and may be the same or different in each bracketed moiety of the formula, except that all .alpha.'s are not all zero;
- m and n are integers
- where
- m>3
- n.gtoreq.0 and
- m+n is from 11 to 19;
- and at least one alkylene oxide in a ratio of moles of alkylene oxide to equivalents of hydroxyl in said polyester polyol from about 0.5:1 to 5:1.
