Über zwei gruppen von relaxationsübergängen im polybutadien und seinen copolymeren oberhalb der glastemperatur

Abstract

We studied the continuous spectra of relaxation time, spectra of internal friction and heat capacity of atactic polybutadiene and its copolymers, which contained 26 and 50% acrylonitrile units. The physical nature of relaxation transitions above the glass transition temperature identified and calculated their characteristics.
