ABSTRACT OF THE INVENTION Novel blends of polymers are produced by polymerizing inter- reactive compounds that form polymers in a non-free radical polymerization, and at least one monomer possessing carbon-to-carbon double bonds capable of polymerization by means of a free radical mechanism, in the presence of reactive initiators. In a preferred mode, a reaction mixture is formed comprising the interactive compounds, the monomers, and the reactive initiators. The interactive compounds are reacted in a initial step to form a first polymer connected to the the reactive initiator promote polymerization of the monomers to form a second polymer. The first polymer forms the continuous phase of the blend, while the second polymer comprises the discontinuous phase. As a consequence of the enhanced inter-phase adhesion resulting from the interaction of the reactive initiators with both polymers, the blends display superior tensile strengths, elastic recovery, and increased elongation at break.
