Sym. fully liquid-crystalline triblock copolymers of various structures containing optically active mesogenic groups are for the first time synthesized via pseudo-living radical reversible addition-fragmentation chain-transfer polymerization Their phase behavior and physicochem. and optical properties are studied. It is shown that, depending on composition, at low temperatures block copolymers can form at temperatures phase-separated structures caused by microsegregation of blocks of different chem. natures and that, with an increase in temperature, these structures can mix to form a cholesteric mesophase characterized by a helical supramol. structure. A model illustrating the mol. packing of block copolymers with a phase-separated lamellar structure is advanced. The effect of the mol. structure of the block copolymers on their optical properties is discussed. In the experiment, the researchers used many compounds, for example, Benzyl benzodithioate (cas: 27249-90-7Safety of Benzyl benzodithioate).
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. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Safety of Benzyl benzodithioate
