Free radical terpolymerization of three non-homopolymerizable monomers, 1 - Kinetic scheme

In previous papers two models were proposed which describe the terpolymeriz ation of non-homo-polymerizable donor and acceptor monomers. The first one is based on the terminal model considering only the propagation reactions o f the free monomers. The second one is the complex model considering only t he reactions of charge-transfer complexes. This paper describes a new kinet ic scheme involving the participation of both the free monomers and the cha rge-transfer complexes. Quantitative treatment of the overall polymerizatio n rate by this new kinetic scheme allows to evaluate the degree of the part icipation of the free monomers and the charge-transfer complexes. For the f irst time therefore it is possible to determine quantitatively the influenc e of charge transfer complexes on the free radical terpolymerization of non -homopolymerizable monomers.
