THE BASIC PROCESSES OF DEPOLYMERIZATION AND ITS REAL KINETIC-ANALYSIS

The method of computer-experiments can be applied successfully on the radical depolymerization under inclusion of initiation, depropagation and termination. The comfortable PC-program 'TA-kin' for the non-linea r estimation of parameters for TG- or DSC-experiments was applied to t he determination of activation parameters of depropagation and termina tion. Therefore the overall-evaluation of three or more data sets is a prerequisite. The determination of kinetic parameters runs satisfacto ry if the measured curves are strongly different, e.g. by varying the heating rate, including acceptable experimental errors. Several recomm endations for laboratory experts are given. A great support for a very sufficient estimation is the inclusion of simultaneous analysis of th e radical concentration.
