ABSTRACT:
The resins resulting from converting dicyclopentadiene-phenol adducts to their corresponding vinylbenzyl ethers are an excellent matrix in which to embed fibers to produce a composite. Such resins, especially as a blend of materials with varying molecular weight distribution, are amorphous materials whose glass transition temperature is well under the curing temperature, and whose solubility permits solutions with high solids content so as to afford coatings with high resin content. The extensively crosslinked polymer resulting from therma, photochemical, or free radical initiated polymerization has excellent thermal and electrical properties for use in multilayer circuit boards.
