Abstract

Flexible thermoplastic epoxy resins are prepared by reacting (1) an advanced epoxy resin prepared by reacting a mixture of an aromatic based epoxy resin and an aliphatic based epoxy resin with a polyhydric phenol in the presence of an advancement catalyst with (2) a monocarboxylic acid or anhydride thereof; reacting the resultant product with a mixture of an aromatic based epoxy resin and a monofunctional material reactive with vicinal epoxy groups; and reacting the resultant product with a carboxyl terminated elastomer. These resins are particularly useful in formulating pavement marking paints.
