ABSTRACT:
The present invention provides an improved process for producing blends of tackifying resins and low molecular weight polyphenylene ether resins. This invention involves combining the resin solutions or redissolving one of the resins once isolated, in the other resin solution and isolation of the resin blend by devolatilization, precipitation, evaporation, spray drying, and/or stripping of the organic solvent.
