1. A process for production of rosin resin comprising the steps of:
a) heating with agitation previously melted rosin to a temperature in the range of 200 to 260° C. and adding an acrylic copolymer; and b) adding a source of divalent metal and allowing to react at a temperature in the range of 200 to 260° C. until a constant viscosity transparent resin is obtained. |
