Patent ID: 8871870

Claim:
A method of preparing a synthesized base resin by the steps of: admixing in the presence of a solvent, from about 1 to about 99 wt % of at least one unsaturated polyolefin polymer and from about 1 to about 50 wt % of at least one monomer of a mono maleimide, a bismaleimide and combinations thereof; adding an initiator to the admixture to form a reactive mixture; heating the reactive mixture to a temperature of from about 90 to about 105° C. and allowing the reactive mixture to react for a period of time sufficient for the reactive mixture to reach a viscosity of from about 300-1000 cP measured at 25° C.; and adding an inhibitor to the reactive mixture to stop the reaction wherein the admixture does not include a polyphenylene ether.
