Реферат: Disclosed are beta -aminoacrylic-acid ester derivatives containing polyalkylpiperidine groups and having the formula (I), in which n is a number from 1 to 50; R<1> and R<2>, which may be the same or different, are hydrogen, C1-C6 alkyl, formyl, C2-C6 alkanoyl, C1-C12 alkoxy, C5-C6 cycloalkoxy, Cyanomethyl, 2-hydroxyethyl, benzyl or a group of the formula -CR<3>=CH-CO-OR<4>, R<3> being hydrogen, C1-C6 alkyl or a group of the formula -CO-OR<4> and R<4> being C1-C18 alkyl, C5-C8 cycloalkyl, C7-C18 aralkyl, phenyl or tolyl; A is C2-C12 alkylene, C5-C8 cycloalkylene, phenylene, biphenylene or a group of the formula (a), (b), (c), (d) or (e) in which m is 2 or 3. If n = 1, Y is hydrogen, C1-C18 alkyl, formyl, C2-C18 alkanoyl, C7-C18 aralkyl or a group of the formula -CH=CH-CO-O-Z; B is a direct linkage and Z is C1-C18 alkyl, C5-C8 cycloalkyl, C7-C18 aralkyl, phenyl, tolyl or a group of the formula -CCH2CH2O)pH or --[CH(CH3)CH2O]pH, p being a number between 1 and 30, and, if n > 1, Y is hydrogen or a group of the formula (f); B is a bridging group of the formula -CH=CH-CO-O-X-, Z being bonded to the C-C double bond in B; X is C2-C18 alkylene, C5-C8cycloalkylene, phenylene, biphenylene or a group of the formula -(CH2CH2O)qCH2CH2- or -[CH(CH3)CH2O]qCH(CH3)CH2-, q being a number from 1 to 30, and Z is a group of the formula (g or h).
