DE 3313574 A1 20 Oct 1983, 69 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: G03C001-06; G03C001-82; G03C011-10. APPLICATION: DE 83-3313574 14 Apr 1983. PRIORITY: JP 82-61937 14 Apr 1982. DOCUMENT TYPE: Patent CA Section: 74 (Radiation Chemistry, Photochemistry, and Photographic and Other Reprographic Processes) UV-absorbing (300-400 nm) polymeric latex which prevents UV degrdn. of Ag halide photog. emulsions and films consists of a homopolymer or a copolymer with a repeating unit of the formula CH2:CRZ(Z1)m(Z2)nR1 (I: R = H, C1-4 alkyl, or Cl; Z = CONH, CO2, or C6H4; Z1 = C1-20 alkylene or C6-20 arylene; Z2 = CO2, OCO, CONH, NHCO, SO2NH, NHSO2, SO2, or O; m = 0 or 1; n = 0 or 1; and R1 = UV absorbing group derived from a compd. of the formula R2R3NCH:CHCH:CR4R5 where R2 and R3 = H, C1-20 alkyl, and C6-20 aryl or together form a ring; R4 = CN, CO2R6, CONHR6, COR6, or SO2R6; R5 = CN, CO2R7, CONHR7, COR7, or SO2R7; and R6 and R7 = C1-20 alkyl or C6-20 aryl or together form 1,3-dioxocyclohexane, barbituric acid, 1,2-diaza-3,5-dioxocyclopentane, or 2,4-diaza-1-alkoxy-3,5-dioxocyclohexane group). Thus, in the prepn. of P-CH2:CHC6H4SO2C(CO2Et):CHCH:CHNEt2 (I), 3-anilinoacroleinanil and Et (4-vinylphenyl)sulfonylacetate were reacted in acetic anhydride, and the product after removal of the anhydride was reacted with EtOH and Et2NH. Then, I was copolymd. with Me methacrylate to form the polymeric latex which was dispersed in gelatin. A layer of this dispersion coated on a cellulose triacetate support showed high UV absorption and in a Ag halide colored film gave good color fastness and high image contrast. .

Solid-phase synthesis of 4,5-disubstituted 1,2,3-triazoles. Li, Chenxi; Huang, Wenqiang; Lu, Yu; He, Binglin (Inst. Polym. Chem., Nankai Univ., Tianjin 300071, Peop. Rep. China). Chin. Chem. Lett., 2(10), 773-4 (English) 1991. 3132-99-8 and 7605-30-3 are also in the experiment. CODEN: CCLEE7. DOCUMENT TYPE: Journal CA Section: 28 (Heterocyclic Compounds (More Than One Hetero Atom)) Treating Na polystyrenesulfinate (Ps-SO2Na, Ps = 2% crosslinked polystyrene) with BrCH2CO2Et and KI in DMF contg. Bu4N+I- gave PS-SO2CH2CO2Et which was condensed with XC6H4CHO (X = H, p-Me, m-Me, p-Cl, m-Br, p-MeO, p-O2N) in C6H6 contg. piperidine to give PS-SO2C(CO2Et):CHC6H4X. The latter was treated with NaN3 in DMSO 5h at 120° to give 15-30% triazoles I. .
