Abstract
The instant invention relates to an epoxy/alkylation-type hydrocarbon resin alloy comprising an epoxy resin, an alkylation-type hydrocarbon resin, and a curative. The alkylation-type hydrocarbon resin is characterized as a product formed by an alkylation reaction between a cyclic diolefin and aromatic solvent. A particularly effective alkylation-type hydrocarbon resin in this invention is the alkylation resin formed by the reaction of dicyclopentadiene (DCPD) with alkylnaphthalene solvent. The alkylation-type hydrocarbon resin can be readily dissolved into various epoxy resins and easily processed into resin impregnated glass cloth prepreg for ultimate conversion into electronic laminate products. These epoxy/alkylation-type hydrocarbon resin alloys retain high Tg values with minimal increase in thermal expansion.
