Coating of steel plate

Coating of steel plate. Otsuki, Akira; Konno, Ryozo; Aoki, Atsushi (Toyo Ink Mfg. Co., Ltd., Japan). Japan. Kokai JP 52099918 22 Aug 1977 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C21D009-46. APPLICATION: JP 76-15493 17 Feb 1976. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Section cross-reference(s): 55 Steel plate is coated with UV-hardenable, oxidn.-resistant paint contg. carbonate and (or) hydroxide and optionally, metal oxides as filler, irradiated, and annealed. Thus, glycerol-epichlorohydrin copolymer, acrylate [65547-16-2] 40, Alonix M8030 [61287-25-0] (oligoester acrylate) 40, Alonix M6100 [61287-24-9] (oligoester acrylate) 20, 8:1 benzophenone-4,4'-bis(di-Et amino)benzophenone mixt. 4, kaolin 70, and basic Mg carbonate [39409-82-0] 3 parts were mixed, applied at a 10m thickness on electromagnetic steel plate, UV-irradiated, and annealed 3h at 760° to give a nonflaking coating.

Olefin polymerization catalyst

Olefin polymerization catalyst. Kochhar, Rajindar K.; Rowatt, Robert J. (Gulf Research and Development Co., USA). U.S. US 4016344 5 Apr 1977, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08F004-66. NCL: 526124000. APPLICATION: US 71-159043 1 Apr 1971. DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) Dicumyl peroxide (I) [80-43-3]-treated MgO [1309-48-4] or -basic magnesium carbonate [39409-82-0] supports for Ziegler polymn. 39409-82-0 and 9003-07-0 which are cas registry numbers are also used here. catalysts gave higher yields of polyethylene (II) [9002-88-4] or polypropylene [9003-07-0] per gram of catalyst than did supports not treated with I. Thus, 20 g MgO (99.0% 325 mesh) in 20 mL MeOH was treated with 0.54 g I for 45 min, the MeOH was removed, the treated MgO was dried in vacuo at 50.degree. for 3 h, mixed with 50 mL TiCl4 and washed 10 times with heptane. Then, 0.2 g of this catalyst support with 2 mL 25% soln. of iso-Bu3Al [100-99-2] was used to polymerize ethylene at 75.degree./40 psig for 1 h giving 195.7 g II, equal to a yield of 978.5 g II/g catalyst/h, compared with 719 for MgO not treated with I. .
