Multichromophoric ultraviolet stabilizers for organic compositions: Multichromophoric ultraviolet stabilizers for organic compositions. Wang, Richard H. S.; Irick, Gether, Jr. (Eastman Kodak Co., USA). U.S. US 4043973 23 Aug 1977, 9 pp. Division of U.S. 3,936,419. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08K005-47. NCL: 260045800NT. APPLICATION: US 74-511570 2 Oct 1974. DOCUMENT TYPE: Patent CA Section: 36 (Plastics Manufacture and Processing) Section cross-reference(s): 28 The title stabilizers for plastics are prepd. contg. .gtoreq. 1 heterocyclic group connected to a hydroxybenzophenone, hydroxyphenylbenzotriazole, or hydroxystyrene residue. Thus, 0.18 mol monoterephthaloyl chloride [7377-26-6] in 125 mL THF was slowly added to a soln. of 0.09 mol H2NNH2 and 15 g NaHCO3 in 150 mL H2O to form di-Me 4,4'-(hydrazodicarbonyl)dibenzoate [24000-79-1] (m.p.There are some reagents like 58764-17-3 is used in this study. 295-8.degree.) in a quant. yield, which (0.056 mol) was refluxed in 100 mL POCl3 and 200 mL PhMe for 6 h to obtain 80% di-Me 4,4'-(1,3,4-oxadiazole-2,5-diyl)dibenzoate (I) [7531-07-9]. A soln. of 0.042 mol I and 0.1 mol KOH in 700 mL 60% EtOH was refluxed 10 h and acidified with 6N HCl to form the corresponding bis acid [41259-89-6], which was refluxed (0.013 mol) with 50 mL SOCl2 in 200 mL PhCl for 10 h to produce 90% 4,4'-(1,3,4-oxadiazole-2,5-diyl)bis(benzoyl chloride) (II) [40874-25-7]. A soln. of 0.016 mol II in 150 mL CHCl3 was added to 0.023 mol 2,4-dihydroxybenzophenone [131-56-6] and 0.023 mol NaOH in 50 mL H2O, and the mixt. was refluxed 4 h to yield 70% bis(4-benzoyl-3-hydroxyphenyl) 4,4'-(1,3,4-oxadiazole-2,5-diyl)dibenzoate (III) [58764-10-6]. An extruded poly(tetramethylene terephthalate) [24968-12-5] bar contg. 0.5% III had flatwise impact strength 19, 20, and 20 initially, after 300 h, and after 500 h exposure to a Hg lamp, resp.; compared with 17, 6, and 6, resp., for the polymer without the III. Similarly prepd. were 8 other UV stabilizers. .

Photopolymerizable polymeric compositions containing halogen-containing aromatic ketones: Photopolymerizable polymeric compositions containing halogen-containing aromatic ketones. Pacifici, James G.; Newland, Gordon C.; Beard, Hobert M., Jr. (Eastman Kodak Co., USA). U.S. US 4040923 9 Aug 1977, 7 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08F008-00. NCL: 204159150. APPLICATION: US 76-692403 3 Jun 1976. DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) Section cross-reference(s): 25 (Halomethyl)methoxycarbonylbenzophenones are useful as photocrosslinking catalysts for unsatd. polyester coatings and as photopolymn. catalysts for compns. contg. unsatd. monomers. Thus, PhMe [108-88-3] reacted with 4-methoxycarbonylbenzoyl chloride [7377-26-6] in the presence of AlCl3 to give 4'-(methoxycarbonyl)-4-methylbenzophenone [64141-11-3] which was chlorinated with SO2Cl2 giving 4-chloromethyl-4'-methoxycarbonylbenzophenone (I) [64141-12-4]. Maleic anhydride-propylene glycol copolymer [25749-49-9]-styrene coating contg. I was crosslinked in 1 min by an 80-W/in. UV lamp to a coating contg. 22.3% extractable content compared with 72.3% for a similar coating contg. no crosslinking catalyst and 46.2 and 76.4% for similar coatings contg. 7:1 benzophenone-Michler's Ketone and .alpha. 64141-15-7 is just another one chemical used in this study.-chloroacetophenone as crosslinking catalysts, resp. .
