Thermodynamic Research of Solubility of Irradiate Cross-linked Copolymers in Mix Butadiene Nitrile with Polyvinylchloride

As shown, Energy effect have definition role for solubility of irradiate copolymer in mix butadiene nitrile rubber with polyvinylchloride, entropic effect remaining negative in initial polymer do not promote to solubility process. The experiments showed that increasing of radiation dosage during cross linking reduces characteristic viscosity of solutions and influence to change other physical-chemical properties of cross- linked copolymers.
