- W2050900738 abstract "Kinetic analysis of the photo-degradation of polymethylmethacrylate above 160° C involves the determination of three constants: I , the rate of initiation, k d the rate constant for depropagation, and k t the rate constant for termination. It is shown that I may be estimated from retardation experiments, and also from molecular-weight measurements. Determination of the lifetime of the kinetic chains using the rotating-sector technique and a continuously recording Pirani gauge makes it possible to evaluate k d and k t . It is shown that the value of k d is in reasonable agreement with theoretical predictions, and leads to an acceptable value of the entropy of polymerization. k t is abnormally small compared with radical termination reactions in dilute solution. This is interpreted as a ‘gel effect’ due to the abnormal conditions under which the reaction occurs in a highly viscous polymer." @default.
