Abstract:
A method for preparing a polymeric polyol which comprises copolymerizing a multifunctional epoxide resin and water in the presence of an amount of acid effective for polymerizing the epoxide resin and the water, wherein the epoxide resin comprises at least one epoxide resin selected from the group consisting of diglycidyl ether of bisphenol-A, an advanced diglycidyl ether of bisphenol-A, diglycidyl ether of bisphenol-F, an epoxy novolac resin, and diglycidyl ether of resorcinol, the amount of water being sufficient to avoid gelation, the copolymerization being a non-dispersion process and performed in the presence of a solvent that substantially dissolves both the epoxide resin and the water.
