FTIR-Thunderdome Thermooxidation Studies of High Temperature Acrylate Elastomers - (PPT)

摘要

The induced thermooxidation process at 175°C modifies the mechanical properties of ACM according to the 3 following mechanisms: - oxidation on the secondary C atom of the acrylic units - anhydride formation on the MEA units - oxidation in α position of O atom on MEA units - In case of MEA oxidation a hardening of the ACM is observed - Correlation between these studies and industrial experience (e.g. improved thermooxidation stability of HTACM in comparison to standard grades) could be proven.
