Peroxide induced crosslinking and degradation of polyvinyl chloride

Peroxide induced crosslinking and degradation of polyvinyl chloride (PVC) were experimentally investigated using an on‐line electron spin resonance (ESR) spectroscopy technique. The reaction variables included temperature, peroxide type and concentration. A single line ESR spectrum was observed with its peak‐to‐peak width decreasing during the reaction. The mechanism involved in the reaction was elucidated based on the radical information. The …
