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 C 2 to C 9 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 C 1 to C 7 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.

The present invention relates to polymeric compositions for controlled release or delivery of pharmacologically active agents. Each polymeric composition comprises a biocompatible polymeric matrix containing at least one pharmacologically active agent that is susceptible to oxidative degradation. The biocompatible polymeric matrix comprises at least a first polymeric material with an active antioxidant functional moiety covalently bound thereto in sufficient amount for protecting the at least one pharmacologically active agent against oxidative degradation. Optionally, the biocompatible polymeric matrix further comprises a second polymeric material that is essentially free of covalently bound active antioxidant functional moiety.
