First Claim
Patent Images
1. A modified amino polyol for use in preparing flexible polyurethane foams, the modified polyol produced by reacting:
- (1) an initiator having an active hydrogen functionality of from 3 to 4,(2) one or more alkylene oxides,(3) an amino alcohol adduct in such a manner that the adduct is added internally along the length of the polyol chain, the amino alcohol adduct being the reaction product of;
(a) an epoxy resin and(b) an amino alcohol of the formula;
##STR4## wherein;
x ranges from about 1 to 4,y ranges from about 1 to 40, andR is an alkyl radical of from 1 to 4 carbon atoms.

Abstract
Polyether polyols are modified by reaction with alkylene oxides and amino alcohol-epoxy resin adducts. The adducts are the reaction product of an epoxy resin and amino alcohol of the formula: ##STR1## wherein: x ranges from 1 to 4,
y ranges from 1 to 40, and
R is an alkyl of from 1 to 4 carbon atoms.
These polyether polyols are used to prepare flexible polyurethane foams.
