Abstract
Abstract Unsaturated polyol compounds containing alkenyl aryl constituents are described. These unsaturated polyols are prepared by reacting a polyol with an aromatic derivative including both an alkenyl constituent and a second functionality reactive with a polyol. The resulting unsaturated polyols feature an alkenyl aryl constituent which enhances polyol receptivity for graft copolymerization with vinyl monomers. The aryl constituent along with multiple hydroxyl groups of the polyol render these polyols particularly suitable for polyurethane end uses.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
69 words
An ethylenically unsaturated alkenyl aryl polyol characterized by the formula: ##STR11## wherein R 1 is hydrogen or methyl; R 2 represents a lower alkylene radical of 1-4 carbons; and --O--R 3 --(OH) 2 ) represents a residue of a polyether polyol, R 3 (OH) 3 , wherein R 3 represents a polyether chain, with an equivalent weight ranging from 1000 to 1500, after removal of one hydroxy hydrogen therefrom.
Claim 2
Dependent Claim
69 words
An ethylenically unsaturated alkenyl aryl polyol characterized by the formula: ##STR11## wherein R 1 is hydrogen or methyl; R 2 represents a lower alkylene radical of 1-4 carbons; and --O--R 3 --(OH) 2 ) represents a residue of a polyether polyol, R 3 (OH) 3 , wherein R 3 represents a polyether chain, with an equivalent weight ranging from 1000 to 1500, after removal of one hydroxy hydrogen therefrom.
Claim 3
Dependent Claim
13 words
The unsaturated polyol of claim 1 wherein R 2 represents --CH 2 --.
Claim 4
Dependent Claim
11 words
The unsaturated polyol of claim 1 wherein R 1 is hydrogen.
Claim 5
Dependent Claim
25 words
The unsaturated polyol of claim 1 wherein R 3 comprises a polyether chain derived from a single alkylene oxide or a mixture of alkylene oxides.
Claim 6
Dependent Claim
26 words
