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 reactive initiator. In a subsequent reaction, free radicals derived from 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.
新型聚合物混合物是通过在非自由基聚合过程中形成聚合物的相互反应化合物和至少一种具有碳碳双键、能够通过自由基机制聚合的单体在反应引发剂存在的情况下聚合而成。在一种优选模式中,反应混合物由互作化合物、单体和活性引发剂组成。交互式化合物在初始步骤中发生反应,形成与活性引发剂相连的第一种聚合物。在随后的反应中,活性引发剂产生的自由基促进单体聚合,形成第二种聚合物。第一种聚合物构成混合物的连续相,而第二种聚合物构成不连续相。由于活性引发剂与两种聚合物的相互作用增强了相间的粘附性,混合物显示出优异的拉伸强度、弹性恢复和断裂伸长率。
