HYDROXYLATED PERFLUOROALKYL POLYETHERS, PROCESS FOR THEIR PREPARATION AND APPLICATION IN THE SYNTHESIS OF POLYURETHANE MATERIALS

摘要

(57) Abstract Is displayed with formula (A) to possess the perfluoroalkyl conversion side chain which, R _F to be the per fluorine conversion basis which possesses 1 - 20 carbon atoms with upper formula, as for R₁ [(CH₂) _mC (R₂ R₃) -] the basis be the basis where it is possible to have 1 genera or the multiple hydroxyl conversion bases which differ, n 1, 2, 3 or 4 to be the integer which is, R₂ and R_{3 the} equality which is displayed with general expression (CH₂) _pX or to be the basis which differs, p=0 or 1 be here, as for X hydrogen,It is the basis which is chosen from the base, methyl, O alkyl or allyl ether, x is the quantity of 1 - 25, y is number 0 - 25, m is 1, 2 or 3, hydroxyl conversion poly ether. Aforementioned poly ether is the precursive body of the fluorine conversion polyurethane, it is possible to be able with the cationic polymerization of the monomer which designates the perfluoroalkyl conversion oxy run in the inactive organicity solvent as the base.
