A plasticizer-resistant bonding composition based on oligodieneurethane epoxy rubber

A study on creation of plasticizer-resistant bonding composition for bonding of a highly filled polymer composition, which is based on butadiene nitrile rubber plasticized by a polar plasticizer, with a rigid multilayer substrate has been performed. Rheokinetic regularities of curing of the bonding composition based on oligodieneurethane epoxy rubber in relation to the content of quinolic ether used as a curing agent have been studied. The constants of the processes of viscous flow, curing, and gelation of the bonding composition have been calculated. Physical and mechanical characteristics of the bonding composition, its glass-transition temperature, and swelling in a polar plasticizer, as well as the strength of bonding with a highly filled polymeric composition, have been determined.
