Peroxide Induced Crosslinking and Degradation of PA

Abstract Peroxide induced crosslinking and degradation of nylon-12 were experimentally investigated using an on-line electron spin resonance (ESR) spectrometer. It was found that different types of polymer radicals were involved in various peroxide modification processes. Five-line ESR spectra were observed in the DCP/nylon-12 and TBPB/nylon-12 systems, while the L130/nylon-12 system gave a three-line spectrum initially, followed by a …
