Abstract: A continuous process comprising: a) separating a starting epoxy novolac resin comprising oligomers having an average functionality of greater than 2.5 and a hydrolyzable chlorine content of less than 450 ppm with a first continuous evaporator apparatus under a vaporization temperature in the range of from 150° C. to 250° C. and an absolute pressure of from 0.05 to 1 mmHg absolute to form a first vapor fraction comprising epoxy novolac resin having more than 95 weight percent of 2-functional components and wherein the mass of the first vapor fraction is in the range of from 5 to 20 weight percent of the starting epoxy novolac resin; and a first bottom fraction comprising epoxy novolac resin having a lower weight percent of 2-functional components in comparison with the weight percent of 2-functional components of the starting epoxy novolac resin; b) recovering the first bottom fraction; and c) condensing from 95 weight percent to 99.

Abstract: A conductive curable resin composition including (a) at least one vinylarene oxide, (b) at least one curing agent, and (c) at least one conductive filler; a process for making the above curable resin composition; and a cured resin composition made therefrom. The curable resin composition when cured produces a thermoset having a higher heat resistance after cure than analogous prior art compositions. The curable compositions of the present invention are advantageously useful, for example, as a die attach adhesive for semiconductor packaging material thermoset materials.
