Abstract
Samples of modified 1,2-polybutadiene were prepared by the reaction of the polymer with peracetic acid or tert-butyl hydroperoxide in the presence of a catalyst, hexacarbonylmolybdenum. The hydrodynamic characteristics of dilute solutions and the rheological properties of concentrated solutions of the starting and epoxidized polydiene in hydrocarbon solvents were studied. The Huggins constant K x, second virial coefficient A 2, root-mean-square size of macromolecular coils $$(\overline {R^2 } )^{1/2} $$ , and the enthalpy, entropy, and Gibbs energy of activation of the viscous flow of solutions of the starting and modified polydiene were estimated.
