摘要： 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.

摘要： The present invention discloses a process for stabilizing polyolefin compositions against the deleterious effects of melt processing, heat aging and exposure to combustion products of natural gas, which process comprises incorporating or applying to a polyolefin an effective stabilizing amount of a tris-(mono-alkyl)phenyl phosphite ester of the formula I, or a mixture of phosphite esters of formula I, where each R is the same or different and is straight or branched chain alkyl of from 1 to 8 carbon atoms, and where said phosphite ester or phosphite ester mixture is in the liquid state at 25° C. and 1 atm of pressure. Also disclosed is a stabilized composition comprising polyolefin and a present phosphite ester or phosphite ester mixture as well as certain mixtures of tris-(mono-alkyl)phenyl phosphite. The present liquid phosphite ester stabilizers are especially compatible with low density polyethylene.
