Methods of making stable and thermally polymerizable vinyl, amino or oligomeric phenoxy benzocyclobutene monomers with improved curing kinetics

A method of making a monomer comprises:

• deprotecting or deacylating an organic alkali cleavable protecting group containing aromatic monomer selected from the group consisting of an addition polymerizable group containing aromatic monomer, an amine containing aromatic monomer, and an oligoaromatic phenol compound containing a phenolic hydroxyl by hydrolyzing it to remove the protecting group in organic alkali in a polar solvent containing an excess of alkali C1 to C7 alkoxide to form an hydroxyl functional addition polymerizable aromatic monomer, hydroxyl functional aromatic amine functional group containing monomer or hydroxyl functional oligoaromatic compound, followed by;
• reacting via nucleophilic substitution the resulting hydroxyl functional addition polymerizable aromatic monomer, aromatic amine functional group containing aromatic monomer or oligoaromatic compound with an alpha-halide (α-halide) or strong acid conjugate leaving group containing arylcyclobutene compound in a polar solvent, to yield an arylcyclobutene-containing addition polymerizable aromatic monomer, aromatic amine containing 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.
