“…Block copolymers of these monomers with VAc allow the preparation of PVA-PVAc block copolymers by selective hydrolysis [9,34]. The increased electronegativity of the ester substituent had a negligible effect on the degree of control over the polymerization.…”

“…Playing on the free volume of the polymer chain and the strength of polymer-polymer interactions can also influence the behavior of poly(vinyl ester)s in solution. A recent example is the solubility of PVAc in supercritical carbon dioxide (scCO 2 ) that can be enhanced via the copolymerization of VAc with hindered [3][4][5][6] or fluorinated vinyl esters [7][8][9]. The kinetics of hydrolysis of the ester group can also be strongly affected by steric hindrance and polar effects.…”

“…The tacticity of polyvinyl esters can be influenced by the use of bulky or polar side groups, or through the control of solvent effects-in particular fluoroalcohols. RAFT polymerization has been used to prepare PVAs with racemic diad content ranging from 53% to 56% [9] by copolymerization of VAc and vinyl trifluoroacetate (VTFAc) in varying proportions. Use of fluoroalcohol solvents such as (CF 3 ) 3 COH at 0 °C allowed the production of narrowly-dispersed PVAc containing up to 62.3% racemic diads [61].…”

This article is the first comprehensive review on the study and use of vinyl ester monomers in reversible addition fragmentation chain transfer (RAFT) polymerization. It covers all the synthetic aspects associated with the definition of precision polymers comprising poly(vinyl ester) building blocks, such as the choice of RAFT agent and reaction conditions in order to progress from simple to complex macromolecular architectures. Although vinyl acetate was by far the most studied monomer of the range, many vinyl esters have been considered in order to tune various polymer properties, in particular, solubility in supercritical carbon dioxide (scCO 2 ). A special emphasis is given to novel poly(vinyl alkylate)s with enhanced solubilities in scCO 2 , with applications as reactive stabilizers for dispersion polymerization and macromolecular surfactants for CO 2 media. Other miscellaneous uses of poly(vinyl ester)s synthesized by RAFT, for instance as a means to produce poly(vinyl alcohol) with controlled characteristics for use in the biomedical area, are also covered.

Vinyl acetate is polymerized in the living way under the irradiation of blue light-emitting diodes (LEDs) or sunlight without photocatalyst at ambient temperature. 2-(Ethoxycarbonothioyl)sulfanyl propanoate is exclusively added and acts as initiator and chain transfer agent simultaneously in the current system. Poly(vinyl acetate) with well-regulated molecular weight and narrow molecular weight distribution (Đ < 1.30) is synthesized. Near quantitative end group fidelity of polymer is demonstrated by nuclear magnetic resonance (NMR) and matrix-assisteed laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS).
