Abstract
The propagation rate coefficient of the terpolymerization of styrene, methyl methacrylate and methyl acrylate in bulk was successfully determined at three different monomer compositions. The temperature was varied between 18 and 80Β°C. The resulting data at 50Β°C were not in agreement with predictions according to the terminal model with binary reactivity ratios that have been determined by fitting copolymer composition data with the terminal model. This indicates that here also the penultimate unit affects the kinetics.

Termination rate coefficients, k t , for the terpolymerization of mixtures containing the three acrylates: methyl, butyl, and dodecyl acrylate or the corresponding members of the methacrylate family: methyl, butyl, and dodecyl methacrylate, have been measured via the single pulse (SP)-PLP technique.
The ternary copolymerizations of glycidyl(methyl) methacrylates (GMA and MMA), styrene (St), and maleic anhydride (MA), considered as acceptor(A 1 )donor-acceptor(A 2 ) systems, were carried out in methyl ethyl ketone in the presence of benzoyl peroxide as initiator at 50 -80Β°C. Constants of copolym
A systematic study of the terpolymerization of butyl acrylate/methyl methacrylate/vinyl acetate (BA/MMA/VAc) was conducted. In this stage of the study, batch emulsion terpolymerizations were performed in a 5 L stainless steel pilot plant reactor. The experiments were designed using a Bayesian (optim
## Abstract **Summary:** This work deals with modeling the terpolymerization of styrene, __Ξ±__βmethylstyrene and methyl methacrylate in the presence of an inhibitor. The model used is a βtendency modelβ based on the kinetics of the complex elementary chemical reactions both in the aqueous phase and
