| titleOfInvention | Carbodithioic acid PFBBR ester and its preparation method and application |
| abstract | The invention discloses a kind of carbodithioic acid PFBBR ester and its preparation method and application, the structural formula of carbodithioic acid PFBBR ester is Its preparation method is using five fluorine bromo-hydrocarbons as substrate, substrate is reacted under catalysis of iodine with magnesium powder or substrate reacts Grignard reagent of the synthesis with pentafluorophenyl group end group with ethyl-magnesium-bromide, again with carbon disulfide reaction synthesis dithionate, then with α bromines 2,3,4,5,6 five toluene fluoride esterifications are prepared.The carbodithioic acid PFBBR ester of the present invention can be used as high fluorine-containing RAFT reagents, it is polymerize applied to supercritical carbon dioxide systems with realizing in the RAFT compared with (methyl) fluoroalkyl base ester class fluorochemical monomer under temperate condition, prepares the fluoropolymer with highly stable pentafluorophenyl group end group.Such polymer is in addition to good hydrophobicity, weatherability and resistance to soiling, and high fluorine-containing end group can also lift heat endurance and translucency of polymer etc., so as to meet its application requirement under specific condition. |
