Abstract
The temperature–frequency dependence of the complex elastic modulus of an adhesive composition based on unsaturated polyketone was studied by dynamic mechanical analysis. It was shown that, in the temperature range of –100 to +60°C, two relaxation processes occur, which are related to the presence of two polymer networks in an adhesive composition. The regularities of the effect of γ radiation on the temperature dependence of the complex elastic modulus of an adhesive composition were established.
