Abstract:
An alkylene oxide polymer composition characterized in that said polymer composition has a molecular weight distribution as follows:(a) from about 1 to 19 weight percent based on the total composition of a polymer fraction having a number average molecular weight of from about 100 to 2000 g/gmol;(b) from about 10 to 60 weight percent based on the total composition of a polymer fraction having a number average molecular weight of from about 1000 to 50,000 g/gmol;(c) from about 25 to 89 weight percent based on the total composition of a polymer fraction having a weight average molecular weight of from about 50,000 to 10,000 g/gmol;with the proviso that polymer fraction (a) and polymer fraction (b) do not have the same molecular weight.
