The effect butadiene and acrylonitrile components on the relaxation properties of butadiene-akrylonitrile copolymers

Abstract

The majority of relaxation transitions in poly (butadiene-co- acrylonitrile) that are observed above the glass transitions temperature are connected with the butadiene component. The acrylonitrile component affect the glass transitions temperature and temperature of chemical decomposition of the polymer, and it leads also to the occurrence of the relaxation process connected with the mobility of local dipole-dipole cross bonds.
