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 c, a compound(meth) acrylic unsaturated formula.(x = o, s, nh, nr3 (r3 = alkyl, c1 (12) or o (ch2) n (n =1 - 16): r2 = hydrocarbon chain (linear alkyl or - 20.branched, mono - or polycyclic cycloalkyl or hu00e9tu00e9rocycloalkyleor alkylaryl, comprising an olefinic double bondin the station, or at the end of the line for, oralkyl aryl olefinic double bond or an endocyclic exo - orfor mono - or polycyclic cycloalkyl or hu00e9tu00e9rocycloalkyle.r1 = h or alkyl, and (5) with 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 leasta phase transfer agent, and when the cycloalkyl, r2 =or organic peracid or a hu00e9tu00e9rocycloalkyle polycyclicthe hydrogen peroxide in the presence of at least one hu00e9tu00e9ropoly acid.to open the function is to react with epoxythe epoxide with a compound selected from acids.strong and complex mineral, u00e9thu00e9rates trifluorideboron, acid salts in the presence of the corresponding acid.the halides of trialkyl - or trialcoxy silanes, andketones in the presence of cationic resins.
