Vv. Tereshatov et al., FORMATION OF NETWORK STRUCTURE AND PROPER TIES OF SEGMENTED POLYBUTADIENEURETHANEUREA IN THE PRESENCE OF CHEMICAL INERT PROTON ACCEPTORS, Vysokomolekularnye soedinenia. Seria A, 36(12), 1994, pp. 1988-1994
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.
