Copolymerization Kinetics of a Simple Methacrylate and Functional Comonomers Via Cu(0)‐mediated Reversible Deactivation Radical Polymerization

“…radical system. However as seen in the comparison of our results and literature values, reactivity ratio often shows different values in similar system, as clearly shown in the case of HEMA/MMA . The copolymerization via Cu(0)‐RDRP shows less difference of r MMA and r comonomer values than other methods, strongly suggesting that it can be advantageous to achieve more random sequential structure in functional or reactive copolymer chains.…”

“…Other monomers, however, exhibit significant changes from unity. The pair of MMA and HEMA shows quite different r MMA and r HEMA when the polymerization method is different even if they are radical‐based polymerizations . For the MMA/AMA system, free radical polymerization in bulk exhibits both values close to 0.8, suggesting random copolymerization is feasible, though some literature reported quite different results .…”

Kinetics of cotelomerization of 3-(trimethoxysilyl)propyl methacrylate and perfluorodecylacrylate

“…[24] The extended Kelen-Tüdos method was used to determine r TMSEMA =1.58 and r MMA =0.59 and illustrated that the copolymers had only a soft gradient composition. Perrier et al reported the kinetic study of copolymerization of MMA with PFDA and they showed that conversion of each monomer was almost identical throughout the reaction indicating similar reactivity ratios.…”

“…Ritz et al reported the copolymerization by ATRP of TMSPMA with methyl methacrylate and generated gradient copolymers for applications as compatibilizers for polymer blends or pressure sensitive adhesives. [24] D'Agosto et al also synthesized amphiphilic block copolymers by RAFT technique which can self-assemble into a variety of nano-objects and can be used as colloid stabilizers, nanoreactors, or templates for making inorganic solids. [20] The aim of the work was firstly, the determination of the transfer constant (C T ) of TMSPMA in the presence of 2-mercaptoethanol by telomerization and the check of non-attendance of the side reactions between trimethylsilyl groups and the functional telogen.…”

Synthesis and properties of gradient copolymers of butyl methacrylate and fluorinated acrylate via RAFT miniemulsion copolymerizations

“…There are two types of typical gradient copolymers prepared by CRP. The first type can be called spontaneous gradient, which is prepared by a simultaneous copolymerization method based on the difference of the reactivity ratios between the comonomers . The second type is tailored gradient most prepared by a semibatch technique, in which a monomer is continuously added into a polymerization mixture during the reaction process, and a majority of gradient copolymers have been made by this procedure …”
