PROCESS FOR SELECTIVE EPOXIDATION OF UNSATURATED (METH)-ACRYLATES, NOVEL FUNCTIONAL (METH)ACRYLATES THUS OBTAINED, AND APPLICATION TO THE SYNTHESIS OF NOVEL POLYMERS

摘要

we respond to 10-60.degree.(c) a (meth) acrylic unsaturated compound of the formula: (x = o, s, nh, nr3 (r3 = alkyl, c1 (12) or o (ch2) n (n = 1), r2 = hydrocarbon chain (linear or branched alkyl) - 20.mono - or polycyclic cycloalkyl or hu00e9tu00e9rocycloalkyle or alkylaryl, comprising an olefinic double bond in the station, or at the end of the chain alkyl or aryl and alkyl.olefinic double bond or an exo - or cycloalkyl or hu00e9tu00e9rocycloalkyle endocyclic for mono - or polycyclic alkyl; r1 = h or c1).at least one oxidizing compound (hydrogen peroxide) in the presence of at least one catalyst, alkali molybdates and tungstates) and in the presence of at least one phase transfer agent.and when hu00e9tu00e9rocycloalkyle polycyclic cycloalkyl, r2 = an organic peroxy acid and hydrogen peroxide in the presence of at least one hu00e9tu00e9ropoly acid.to open the function is to react with the epoxy, epoxy compound, selected from among the obtained with a strong mineral acid, boron trifluoride complex u00e9thu00e9rates and.the salts of acids in the presence of the corresponding acid halide, the trialkyl - or trialcoxy silanes, and ketones in the presence of cationic resins.
