Factors Affecting Rates of Comonomer Consumption in Copolymerization Processes with Intermittent Activation

Many controlled polymerization processes proceed via intermittent activation (i.e., by a series of activation/deactivation cycles), and this interrupted growth process may affect not only polydispersities but also (co)polymer microstructure. The computer modeling indicates that, in systems with intermittent and selective activation, rates of consumption of comonomers may be different from conventional systems, and this can result in different copolymer composition, microstructure, and different apparent reactivity ratios. The effect of several parameters such as concentration of the involved reagents, rate constants of homopropagation, cross-propagation, activation, and deactivation on the copolymer composition was studied. Deviations from the conventional systems are predicted for systems such as controlled/living radical polymerization, atom transfer radical polymerization, group transfer radical polymerization, "living" carbocationic polymerization, and other systems with intermittent activation. Use of chiral activators/deactivators may convert stereoselective polymerization to stereoelective polymerization even in the presence of nonselective initiators. The topology of polymers formed by self-condensing vinyl polymerization (branch distribution) may also depend on the dynamics of exchange reactions.

Controlled polymerization causes the final product to have predictable properties, allowing it to have a more diverse application, in turn, increasing its added value. In the present work, a dynamic Monte Carlo (MC) model is used to describe the copolymerization of styrene and n-butyl acrylate through atom transfer radical polymerization (ATRP). A further investigation was performed to estimate the values of kinetic constants with no explicit value reported in the literature using particle swarm optimization (PSO). The model had excellent performance when compared with the experimental data from the literature. The model also provided access to the molecular weight and chemical composition distributions and the polymer microstructures. The results show that the propagation and termination constants' difference affected the polymer structure directly and significantly impacted the distribution curves' broadening. The developed model might be used in the future for monitoring and controlling the average molecular weights and the molecular weight distributions in the chemical process industry.

A crosslinkable terpolymer P(MMA‐BA‐HEMA) was prepared by atom transfer radical copolymerization of 2‐hydroxyethyl methacrylate, methyl methacrylate and butyl acrylate. The structure of the terpolymer was characterized by 1H NMR and gel permeation chromatography. The effects on the polymerization of ligand, initiator, solvent, CuCl2 added in the initial stage and reaction temperature were investigated. The optimal reaction conditions were ethyl 2‐bromopropionate as initiator, CuCl/PMDETA as catalyst, cyclohexanone as solvent, catalyst/ligand = 1:1.5, [M]0:[I]0 = 200:1 and temperature 70 °C. The reaction followed first‐order kinetics with respect to monomer concentration, indicating the best control over the polymerization process, a constant concentration of the propagating radical during the polymerization, efficient control over Mn of the polymer and low polydispersity (Mw/Mn < 1.3). © 2013 Society of Chemical Industry
