Initiation reactivity of anionic polymerization of fluorinated acrylates and methacrylates with diethyl(ethyl cyanoacetato)aluminum was written by Umino, Youhei;Narita, Tadashi;Hamana, Hiroshi. And the article was included in Journal of Polymer Science, Part A: Polymer Chemistry in 2008.Formula: C7H6F6O2 The following contents are mentioned in the article:
Pseudo first-order rate constants of the reaction of diethyl(Et cyanoacetato)aluminum [(C2H5)2Al(NCCHCOOC2H5)] with 17 fluorinated acrylates and methacrylates and five hydrocarbon analogs for references were investigated to examine the initiation reactivities of the anionic polymerization of fluorinated vinyl monomers to afford the reactivity order: CH2=C(CF3)COOC2H5 > CH2=C(CF3)COOCH(CH3)2 > CH2=CHCOOCH2C6F5 > CH2=C(CF3)COOC(CH3)3 > CH2=C(CF3)COOCH2C6F5 > CH2=C(CF3)COOCH(CF3)2 鈮?CH2=CHCOOCH3 > CH2=CHCOOCH2C6H5 鈮?CH2=C(CF3)COOCH2CF3 > CH2=C(CH3)COOCH2C6F5 > CH2=CHCOOCH2CF3 > CH2=CHCOOCH2C2F5 > CH2=CHCOOCH(CF3)2 > CH2=C(CH3)COOCH3 > CH2=C(CH3)COOCH2C6H5 鈮?CH2=C(CH3)COOCH2CH2 C8F17 > CH2=C(CH3)COOCH(CH3)2 > CH2=C(CH3)COOCH2C2F5 鈮?CH2=C(CH3)COOCH2CF3. No rate constants for CH2=C(CH3)COOCH(CF3)2, CH2=CFCOOC(CH3)3, and CH2=CFCOOCH2C2F5 were obtained because of too fast polymerization The incorporation of a trifluoromethyl group into the vinyl group enhanced the reactivity toward the delocalized carbanion. The reactivity of other fluorinated acrylates and methacrylates was concluded to approx. be controlled by the fluorine contents and the bulkiness of substituents of monomers. The reactivity was generally decreased by increasing fluorine contents of fluoroalkyl substituents in ester groups. This study involved multiple reactions and reactants, such as 1,1,1,3,3,3-Hexafluoroisopropylmethacrylate (cas: 3063-94-3Formula: C7H6F6O2).
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. Esters contain a carbonyl center, which gives rise to 120掳 C鈥揅鈥揙 and O鈥揅鈥揙 angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C鈥揙鈥揅 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. Formula: C7H6F6O2
