The mathematical description of polymer chain scission given by N. M.
Emanuel' & D. C. Knorre (Chemical Kinetics (Homogeneous Reactions), John
Wiley, New York, 1973) is shown to be inaccurate and an alternative
formulation is presented. The model of collagen degradation proposed by T.
E. Rudakova & G. E. Zaikov (Polym. Deg. Stab., 18 (1987) 271) which is
based upon the work of Emanuel' & Knorre is modified accordingly. The
revised model is applied to the results of experiments on the effect of
hydrolysis on collagen sutures and is found to fit the data only during the early
stages of degradation. Possible causes of the lack of fit of the conceptual model
are discussed.
