EPOXY NOVOLAC RESINS HAVING A NARROW MOLECULAR WEIGHT DISTRIBUTION AND PROCESS THEREFOR

摘要

Epoxy novolac resins having a narrow molecular weight distribution are prepared by dissolving an epoxy novolac resin prepared by conventional means in a suitable solvent such as xylene, cooling below 50.degree.C until separation into 2 phases occurs, separating the two phases and removing the solvent therefrom thereby producing a resin of relatively low molecular weight and a resin of relatively high molecular weight wherein each resin has a narrow molecular weight distribution.
