METHODS OF MAKING STABLE AND THERMALLY POLYMERIZABLE VINYL, AMINO OR OLIGOMERIC PHENOXY BENZOCYCLOBUTENE MONOMERS WITH IMPROVED CURING KINETICS

摘要

The present invention provides methods of making low energy polymerizable monomers and resins for use in making dielectric materials. The methods comprise deprotecting or deacylating an organic alkali cleavable protecting group containing addition polymerizable, amine containing aromatic monomer or oligoaromatic phenol resin containing an organic alkali cleavable protecting group, such as a C₂ to C₉ alkanoyl group, preferably, an acyl group, by hydrolyzing to remove the protecting group in organic alkali in a polar solvent containing an excess of alkali C₁ to C₇ alkoxide and form a hydroxyl functional monomer or resin, followed by; reacting via nucleophilic substitution the resulting hydroxyl functional monomer or resin with an alpha-halide (a-halide) or strong acid conjugate leaving group containing arylcyclobutene compound in a polar solvent, to yield a product an arylcyclobutene-containing addition polymerizable or amine containing aromatic monomer or oligoaromatic phenol resin having an ether linkage from the cyclobutene ring to an aromatic group of the addition polymerizable aromatic monomer, aromatic amine or oligoaromatic phenol.
