✦ Synopsis

Thermodynamic and hydrodynamic properties of chlorine-containing carbochain polymers in solution were studied. Chemically uniform copolymers (vinyl chloride-vinyl acetate, vinyl chloride-methyl acrylate, vinyl chloride-butyl acrylate, vinyl chloride-vinylidene chloride, vinyl chloride-n-butyl ether, as well as chloropolyethylene and chlorosulphopolyethylene) were investigated. Along with the weightaverage molecular weight )14w, the following parameters were investigated: the molecular-weight distribution of polymers; the dependences of intrinsic viscosities and the second virial coefficient on h~cw; the effect of the polymeric product composition on the magnitude of the swelling degree; the length of the Kuhn segment; the parameter of retardation of internal rotation about a solitary bond. All the chlorinecontaining carbochain polymers investigated (whether plastic or elastomeric) when in solution, were shown to form Gauss impenetrable coils and to possess thermodynamic flexibility. For vinyl chloride copolymers, the hydrodynamic and thermodynamic properties depend on the comonomer content.
