摘要

本文研究了苯乙烯/马来酸酐和马来酸酐/醋酸乙烯在纤维素上的接枝反应，作为将所得到的接枝共聚物用于酶固定化研究的初步研究。接枝具有有效的非稳态特性。人们试图确定接枝反应的初始速率，以便确定各种依赖性。已经确定了k2pkt的值以及相应的平均动力学链长值。随着这些组合中使用的单体体积浓度的增加，这些显著增加。

The radiation-induced graft copolymerisation of styrene/maleic anhydride and maleic anhydride/vinyl acetate onto cellulose

The grafting of styrene/maleic anhydride and maleic anhydride/vinyl acetate onto cellulose from mixed monomer compositions has been studied as a preliminary to the use of the resulting graft copolymers in enzyme immobilisation studies. Grafting has been shown to be effectively non-steady state in character. Attempts have been made to determine initial rates for the grafting reaction so that various dependencies can be ascertained. Values for $k^{2}_{p} k_{t}$ have been determined along with the corresponding mean kinetic chain length values. These increase markedly with increase in the bulk concentrations of the monomers used in these combinations.
