FORMATION OF NETWORK STRUCTURE AND PROPER TIES OF SEGMENTED POLYBUTADIENEURETHANEUREA IN THE PRESENCE OF CHEMICAL INERT PROTON ACCEPTORS

Pecularities of structure formation of polybutadienurethaneurea compos itions in the presence of chemical inert solvents of methylen-bis-o-ch loraniline have been revealed. It was shown that at the same concentra tion of hard segments in elastomers the value of network parameters co nnected with influence of liquids - proton acceptors on self-assotiati on of urea groups. Dependencies of network parameters and physical-mec hanical properties of materials on concentration of such liquids were established. For elastomers with network structure with prevail physic al bonds linear dependence of strength on value of physical network, i n which domains of hard blocks are its knots, it typical.
