Abstract

Homopolymers of chlorotrifluoroethylene (CTFE), vinylidene fluoride (VDF) and methyl methacrylate (MMA) and their copolymers were studied by PGC/IR with regard to the separation and identification of the degraded products and clarification of the degradation mechanism. Besides monomers, HCl CO2, C2H2, HF, C5H10O2, C3F5Cl and dimers are the observed pyrolysis products. Mechanisms for different degradation reactions have also been studied.

Zusammenfassung

Mittels PGC/IR wurden Homopolymere von Chlorotrifluorethylen (CTFE), Vinylidenfluorid (VDF) und Methylmethacrylat (MMA) und deren Kopolymere in Bezug auf die Trennung und Identifizierung der Abbauprodukte und auf die Klärung des Abbaumechanismus untersucht. Aufße den Monomeren wurden HCl, CO2, C2H2, HF, C5H10O2, C3F3Cl und Dimere als Pyrolyseprodukte beobachtet. Mechanismen für verschiedene Abbaureaktionen wurden ebenfalls untersucht.
