    • The present invention discloses liquid cyclic phosphites of for example the formula where n is 1 or 2; when n is 1, R17 is straight or branched chain alkyl of 1 to 18 carbon atoms, when n is 2, R17 is —CtH2t— or —CH2CH2-T3-CH2CH2— where T3 is —S— or >N—R22 where R22 is straight or branched chain alkyl of 1 to 12 carbon atoms and t is an integer of from 2 to 6, R1, R2, R3, R4, R5 and R6 are independently hydrogen, methyl, ethyl, i-propyl, n-propyl, n-butyl, sec-butyl or t-butyl and R is hydrogen. Also disclosed is a stabilized composition comprising polyolefin and a present liquid cyclic phosphite and a process for the stabilization of polyolefin by incorporating therein or applying thereto a present liquid cyclic phosphite. The present liquid phosphite stabilizers are especially compatible with polyolefins.
    • 本发明公开了例如其中n为1或2的式的液体环状亚磷酸酯; 当n为1时,R 17为具有1至18个碳原子的直链或支链烷基,当n为2时,R 17为-C≡C- 2 H 2 - 或-CH 2 CH 2 - - - - 3 CH 2 - 其中T 3为-S-或> NR 22,其中R 22为直链或 - 1至12个碳原子的支链烷基,t为2至6的整数,R 1,R 2,R 3, R 4,R 5和R 6独立地是氢,甲基,乙基,异丙基,正丙基,正丁基,仲丁基 丁基或叔丁基,R为氢。 还公开了包含聚烯烃和本发明的液体环状亚磷酸酯的稳定化组合物,以及通过在其中引入或施加本发明的液体环状亚磷酸酯来稳定聚烯烃的方法。 本发明的液体亚磷酸酯稳定剂与聚烯烃特别相容。
