Abstract
Compounds containing an azo-linkage connecting two similar polyol esters constituents are described. These azo di-ester polyols are prepared by the direct esterification of azo diacids with polyols, in the presence of a strong mineral acid catalyst. The azo di-ester polyol products function as free radical initiators and grafting bases in the graft copolymerization of unsaturated monomers with polyols. These graft copolymers are useful in the formulation of polyurethanes.
