摘要：
Influence of various factors (MM of vinyl-containing polysiloxane, functionality of the crosslinking agent. components ratio) on parameters of vulcanizational networks formed as a result of thermal freatment of polymer-oligomer compositions cured following the hydrosilylation reaction has been studied. Analysis of the change of k and zeta-parameters permits to conclude the difference of the structure of obtained vulcanizational Networks from those described earlier and formed in the presence of a diluent or in the inert medium. The pecularities of vulcanizational networks under study characterized by the strong deviation from affinity are related with proceeding of the side dehydrocondensation reaction.
