Abstract: 1,165,231. Stabilized polyolefines. HERCULES Inc. 2 Jan., 1967 [3 Jan., 1966], No. 98/67. Heading C3P. A polyolefine composition contains 0À02- 10% by wt. of poly(cyclohexylenedisulphide) and 0À02-10% of a hindered phenol. The polyolefine may be stereoregular polypropylene. The sulphide may be of formula where R is H or a C 1-18 alkyl and n is 5-100, e.g. poly-(dipentene-disulphide). The phenol may be a bis(alkylhydroxyphenyl)-alkanoic acid ester, a poly-(alkylhydroxyphenyl) alkane, a poly-(alkylhydroyphenoxy)-substituted triazine of formula where R is an alkylhydroxyphenyl group and R 1 is -OR or thioalkyl group, an alkylphenol/ acetylene condensate containing the repeating unit where R is H or a C 1-20 alkyl group, a thiobis- (alkylphenol) or a polymeric terpene-phenol condensate. In the examples, polypropylene was blended with (1) calcium stearate, 2,4,6-tris- (3,5 - di - tert. - butyl - 4 - hydroxyphenoxy)- 1,3,5-triazine and a poly-(dipentenedisulphide): (2-8) as (1) replacing the triazine by 2,4-bis- (3,5 - di - tert. - butyl - 4 - hydroxyphenoxy)-6- thiooctyl - 1,3,5 - triazine; 1,3,5 - trimethyl- 2,4,6 - tris - (3,5 - di - tert. - butyl - 4 - hydroxybenzyl) benzene; 2,2,4,4 - tetramethyl - 1,3- cyclobutyl - di[bis - (3,5 - di - tert. - butyl - 4- hydroxyphenyl)]-acetate; the polymeric condensate of p-tert. - butyl - phenol and acetylene; the reaction product of n-nonylphenol and acetone; and the condensate of p-tert.-octylphenol, formaldehyde and oxalic acid respectively.
