ABSTRACT:
Thermoplastic epoxy resins are prepared by (A) reacting an advanced epoxy resin prepared by reacting a mixture of (1) a relatively low equivalent weight aromatic based epoxy resin and (2) a (meth)acrylate polymer with (3) a dihydric phenol with (4) a monofunctional compound reactive with vicinal epoxide groups; and (B) mixing the product form (A) with the reaction product of (5) a relatively low equivalent weight epoxy resin and (6) a monofunctional compound reactive with vicinal epoxide groups. The resultant product is substantially free of residual epoxide groups. These resins are particularly useful in formulating pavement marking paints.
