Alkoxylated dihalobutenediol containing compositions

Claim 2

A polyol composition according to claim 1 wherein the oxyalkylene group is oxypropylene or oxyethylene.

Claim 3

A process of preparing a polyol composition which comprises mixing an amine free polyhydroxy compound selected from the group consisting of polyhydroxy alkanes, alkoxylated polyhydroxy alkanes, sugars, alkoxylated sugars, hydroxyl terminated polyesters, and hydroxyl terminated aromatic polyethers and butynediol so that at least 3.5 weight percent of the resulting mixture is butynediol; adding halogen to said mixture in a molar ratio of from about 0.9 to 1.2 mols of halogen per mol of butynediol, at a temperature of less than about 100*C.; and reacting the resulting halogenated product with from 0.5 to 2 mols of alkylene oxide per hydroxyl equivalent of halogenated product; wherein said polyhydroxy compound and the amount of alkylene oxide are so chosen that the final hydroxyl number of the resultant polyol blend is from 200 to 700.

Claim 4

A process for preparing a polyol composition in accordance with claim 4 wherein the weight percent of butynediol is chosen so that the final weight percent of dihalobutynediol moiety in the polyol blend is from 15 to 40 weight percent of the composItion, wherein the hydroxyl number of the polyol composition is from 300 to 600.
