Double bonds were immobilized onto nano-SiO2 via hydrolyzing alkoxysilane moiety of γ-methacryl trimethoxysilane for condensation with hydroxide groups from nano-SiO2. RAFT grafting polymerization of styrene from nano-SiO2 was carried out from the immobilized double bonds, in which azobisisobutyronitrile was used as initiator, 2-cyanoprop-2-yl dithiobenzoate, benzyl dithiobenzoate, benzyl dithiopivalate, 1,2,4-triazolyl-1-carbodithioic acid benzyl ester were used as RAFT agent, resp. Results showed that RAFT grafting polymerization rate of styrene from SiO2 was decided by Z group of RAFT agent. Grafting polymerization of styrene from SiO2 mediated by benzyl dithiopivalate exhibited the highest grafting polymerization rate. In the experiment, the researchers used many compounds, for example, Benzyl benzodithioate (cas: 27249-90-7Related Products of 27249-90-7).
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. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
