Claim 6
Dependent Claim
112 words
A process for the synthesis of a polyalcohol copolymer which comprises the steps of: (a) dissolving a polyborane copolymer in a solvent to form a polymeric solution; (b) introducing an NaOH solution into said polymeric solution at about 25°C; (c) introducing a hydrogen peroxide solution into said polymeric solution at 0°C; (d) heating said polymeric solution to at least about 50°C; (e) maintaining said polymeric solution at at least about 50°C for at least about 1 hour to form said polyalcohol copolymer; (f) cooling said polymeric solution to about room temperature; and (g) precipitating said polyalcohol copolymer from said polymeric solution by the addition of an aliphatic hydrocarbon to said polymeric solution.
