Fremgangsmåde til selektiv epoxidering af umættede (meth)acrylater, fremstillede hidtil ukendte funktionelle (meth)acrylater og deres anvendelse til syntese af hidtil ukendte polymerer
A process for the opening of the epoxide function of a (meth)acrylic epoxide of formula (V): in which: (i) the (meth)acrylic epoxide is reacted with a cpd. of etherate complexes and boron trifluoride, acid salts (in the presence of the corresp. acid), halides of trialkyl- or trialkoxy-silanes - and...

Summary: | A process for the opening of the epoxide function of a (meth)acrylic epoxide of formula (V): in which: (i) the (meth)acrylic epoxide is reacted with a cpd. of etherate complexes and boron trifluoride, acid salts (in the presence of the corresp. acid), halides of trialkyl- or trialkoxy-silanes - and ketones in the presence of cationic resins. (R )(CH2)C-C(O)-X-R (V) X = O, S, NH, NR and O-(CH2)n; R = 1-12 alkyl; n = 3-16; R = H or 1-5C alkyl; R = 2-20 C hydrocarbyl including alkyl, cycloalkyl, mono- or poly-cyclic heterocycle-alkyl or alkylaryl; the hydrocarbon gp. comprises an oxiran gp. in or at the end of the chain (for alkyl or alkylaryl) or as an endo or exo-cycle gp. (for cyclo-alkyl or hetero-cycloalkyl). R may also be glycidyl, 2-oxymethyl-bicyclo-Ä2.2.1Ühept-5(6)yl or epoxy dicyclo-pentenyl- oxyethyl. |
