Copolymers of methyl methacrylate and fluoroalkyl methacrylates: effects of fluoroalkyl groups on the thermal and optical properties of the copolymers was written by Zhou, Dingying;Teng, Hongxiang;Koike, Koutarou;Koike, Yasuhiro;Okamoto, Yoshiyuki. And the article was included in Journal of Polymer Science, Part A: Polymer Chemistry in 2008.Application In Synthesis of 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate The following contents are mentioned in the article:
Fluoroalkyl methacrylates, 2,2,2-trifluoroethyl methacrylate (1), hexafluoroisopropyl methacrylate (2), 1,1,1,3,3,3-hexafluoro-2-methyl-2-Pr methacrylate (3), and perfluoro t-Bu methacrylate (4) were synthesized. Homopolymers and copolymers of these fluoroalkyl methacrylates with Me methacrylate (MMA) were prepared and characterized. With the exception of the copolymers of MMA and 2,2,2-trifluoroethyl methacrylate (1), the glass transition temperatures (Tgs) of the copolymers were found to deviate pos. from the Gordon-Taylor equation. The pos. deviation from the Gordon-Taylor equation could be accounted for by the dipole-dipole intrachain interaction between the Me ester group and the fluoroalkyl ester group of the monomer units. These Tg values of the copolymers were found to fit with the Schneider equation. The fitting parameters in the Schneider equation were calculated, and R2 values, the coefficients of determination, were almost 1.0. The refractive indexes of the copolymers, measured at 532, 633, and 839 nm wavelengths, were lower than that of PMMA and showed a linear relationship with monomer composition in the copolymers. 2 And MMA have a tendency to polymerize in an alternating uniform monomer composition, resulting in less light scattering. This result suggests that the copolymer prepared with an equal molar ratio of 2 and MMA may have useful properties with applications in optical devices. This study involved multiple reactions and reactants, such as 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3Application In Synthesis of 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate).
1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Application In Synthesis of 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate
