Degradation tests A new test procedure to examine p

Degradation of polymers, i.e. main chain scission, seriously impacts the processability and optical and mechanical properties of the end product. Commercial plastics contain additives and antioxidants to minimize the effects of degradation caused during processing. Even with the use of these substances, transport phenomena, including migration of additives, gas and vapour permeability, oxygen absorption and distribution of the additives, influence the kinetics
of thermo-oxidative degradation, degradation (fig. 1) and stabilization. 微量混合流变仪HAAKE MiniLab II
