ABSTRACT:
Phenol-aldehyde novolac resins having reduced quantities of 2-functional material are prepared by removing all or part of the 2-functional material from this product resulting from reacting phenol with an aldehyde. Epoxy novolac resins prepared from the novolac resin containing less 2-functional product exhibit increased Tg values when cured.
