V.;Chernikova, E. V.;Prokopov, N. I.. And the article was included in Russian Chemical Bulletin in 2015.Formula: C14H12S2 This article mentions the following:
The results of comparative kinetic study of the miniemulsion controlled radical polymerization of styrene in the presence of reversible chain transfer agents (benzyl dithiobenzoate and polystyrene dithiobenzoate) and bulk polymerization of similar systems are presented. The influence of the reactant nature and dithiobenzoate concentration of the kinetics of the process is discussed. In the experiment, the researchers used many compounds, for example, Benzyl benzodithioate (cas: 27249-90-7Formula: C14H12S2).
Benzyl benzodithioate (cas: 27249-90-7) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Formula: C14H12S2
