There are disclosed new polymers of piperidine having the general formula:
in which R1, R2, R3, R4, each independently of the others, are an alkyl radical having 1 to 4 C, or R, and R2, and/or R3 and R4 form a cycloalkylene radical having 3 to 12 C, R5 is hydrogen, an alkyl, oxyalkyl or alkoxy radical having 1 to 6 C, or an aryl or an aryl-alkyl radical having 6 to 18 C, an alkenyl radical having 2 to 6 C or a -(CH2)x-CO2-R7 radical in which X is a number from 0 to 12, and R1 = H, a metal, an alkyl, alkylene, alkenyl, alkenylene radical containing 1 to 20 C; R6 = H or an alkyl having 1 to 4 C and n is an integer from 2 to 100.
Use of the piperidine polymers having general formula (I) as stabilizers of polymeric substances, and polymeric compositions stabilized with said piperidine derivatives are also disclosed.
本发明公开了具有通式的哌啶新聚合物:
其中 R1、R2、R3、R4 各自独立地为具有 1 至 4 个 C 的烷基,或 R 和 R2 和/或 R3 和 R4 构成具有 3 至 12 个 C 的环亚烃基,R5 为氢、具有 1 至 6 个 C 的烷基、氧烷基或烷氧基,或具有 6 至 18 个 C 的芳基或芳基烷基、具有 2 至 6 个 C 的烯基或具有 1 至 4 个 C 的芳基烷基、或具有 6 至 18 C 的芳基或芳烷基、具有 2 至 6 C 的烯基或-(CH2)x-CO2-R7 自由基,其中 X 为 0 至 12 的数字,且 R1 = H、金属、烷基、亚烷基、烯基、含 1 至 20 C 的烯基;R6 = H 或含 1 至 4 C 的烷基,n 为 2 至 100 的整数。
此外,还公开了具有通式(I)的哌啶聚合物作为聚合物物质稳定剂的用途,以及用上述哌啶衍生物稳定的聚合物组合物。
