Production of spherical complex antioxidants

Production of spherical complex antioxidants.Some chemicals with cas registry numbers like 87096-80-8 are also used. (Sumitomo Chemical Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59074182 A2 26 Apr 1984 Showa, 5 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C09K015-12. APPLICATION: JP 82-184835 20 Oct 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) A molten mixt. of thioether and phenolic antioxidants is added to an aq. surfactant soln., agitated, cooled, and solidified to obtain antioxidant beads of uniform size, which are free-flowing, do not generate dust when handled, and show good dispersability in polymers. Thus, 25 parts tetrakis[methylene 3-(3,5-di-tert-Bu-4-hydroxyphenyl) propionato]methane [6683-19-8] was added to 75 parts melted dimyristyl thiodipropionate [16545-54-3] under N, and then poured into a stirred soln. of 0.3 part Na N-laurylamino-N-propionate in 500 parts water. The dispersed antioxidant mixt. was cooled and filtered out to obtain 98 parts beads m. 48.5° and ~0.5-2 mm in diam. .

Stabilized polyolefin compositions

Stabilized polyolefin compositions. (Sumitomo Chemical Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 58168641 A2 5 Oct 1983 Showa, 6 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C08L023-02; C08K005-13; C08K005-34; C08K005-36. APPLICATION: JP 82-53385 30 Mar 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Polyolefins with good heat, oxidn., and light stability contain a hindered piperidine compd. (I; R = H, Me; Z = C2-18 alkylene, which may form a ring), tetrakis[methylene 3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionate]methane (II) [6683-19-8], a C12-18 alkyl diester of thiodipropionic acid (III), and (R1SCH2CH2CO2CH2)4C (IV; R1 = C4-20 alkyl) at I-II-III-IV wt. ratio (1-20):1:(0-15):(0-15) and II-(III + IV) wt. ratio 1:(1-15). Thus, polypropylene [9003-07-0] 100, I [R = H, Z = (CH2)4] [51806-80-5] 0.2, II 0.05, and bis(tetradecyl) thiodipropionate [16545-54-3] 0.2 part were mixed with Ca stearate and 2,6-di-tert-butyl-4-methylphenol and fusion kneaded, pelletized, and thermopressed to give a sheet with good heat and oxidn. stability and good weather resistance.
