The possible influence of micrometric-size filler particles on the thermo-oxidative degradation behavior of the polymer chains at polymer/filler interfaces is still an open question. In this study, a cross-linked ethylene-propylene-diene (EPDM) terpolymer filled by aluminum trihydrate (ATH) particles is investigated using (1)H solid-state NMR. The time(More)

Cooperative motions of cis-1,4-polybutadiene (cis-PB) and cis-1,4-polyisoprene (cis-PI) in the bulk state are analyzed and compared using the cooperative kinematics (CK) theory. The mechanisms of relaxation on a local scale are closely similar for the two polymers in dense media, resulting from the same geometry of the backbone, which is the major(More)
