Abstract

A number of physical relaxation processes associated with the decay of various physical crosslinks and also two chemical relaxations attributed to rearrangement of the network and with scission of weak CC bonds have been identified by relaxation spectroscopy in linear or crosslinked filled copolymers of vinylidene fluoride-trifluorochloroethylene (SKF-32) above the glass-transition temperature. Viscoelastic properties and degradation of the elastomer are largely governed by one of the physical relaxation processes related to recombination of polar, pseudo-hydrogen bonds HF.
