Synthesis and exchange reactions of some polymeric benzotriazolides. Ferruti, Paolo; Vaccaroni, Franco; Tanzi, Maria Cristina (Ist. Chim., Univ. Napoli, Naples, Italy). J. Polym. Sci., Polym. Chem. Ed., 16(6), 1435-41 (English) 1978. CODEN: JPLCAT. ISSN: 0449-296X. DOCUMENT TYPE: Journal CA Section: 35 (Synthetic High Polymers) Section cross-reference(s): 63 Three monomeric benzotriazolides (I, Z = NH, Z1 = CH2 [67684-93-9], Z = NH, Z1 = (CH2)5 [67684-94-0], Z = O, Z1 = p-C6H4 [67684-95-1]) were prepd. from 1-H-benzotriazole [95-14-7] and N-methacryloylglycine [23578-45-2], N-methacryloyl-e-aminocaproic acid [59178-92-6], or p-methacroyloyloxybenzoic acid [15721-10-5], resp., and polymd. to give chains to which drug residues could be attached at some distance from the main backbone. The exchange reaction of the three polymeric benzotriazolides with BuNH2 and morpholine were practically quant., while the exchange reaction with MeOH, cyclohexanol, and PhOH had ranges of 24-77, 23-50, and 0-75%, resp. In presence of Et3N, the exchange rates for MeOH, cyclohexanol, and PhOH were 97-100, 42-45, and 92-100%, resp.

Photoresponse of polymethacrylamides bearing 1,3-diphenyl-2-propen-1-one (chalcone) functions in the side chains

Photoresponse of polymethacrylamides bearing 1,3-diphenyl-2-propen-1-one (chalcone) functions in the side chains. Goretzky, Christian; Ritter, Helmut (Fachbereich 9 Organische Makromolekulare Chem., Bergische Univ. Gesamthochschule Wuppertal, Wuppertal D-42097, Germany). Macromolecular Chemistry and Physics, 198(1), 59-69 (English) 1997 Huethig & Wepf. CODEN: MCHPES. ISSN: 1022-1352. DOCUMENT TYPE: Journal CA Section: 36 (Physical Properties of Synthetic High Polymers) Section cross-reference(s): 35, 73 Synthesis and free radical polymn. of 1-(4-methacryloylaminophenyl)-3-phenyl-2-propen-1-one, 1-[4-(6-methacryloylaminohexanoylamino)phenyl]-3-phenyl-2-propen-1- one, and 1-[4-(11-methacryloylaminoundecanoylamino)phenyl]-3-phenyl-2-prope n-1-one are described. The monomers and a model compd. 186319-59-5 and 59178-92-6 which are cas registry numbers are also used here. were characterized by NMR and IR spectroscopy. The corresponding homopolymers and a copolymer with Me methacrylate were characterized by DSC, GPC, and TG anal. and also spectroscopically. Furthermore, the kinetics of E/Z-isomerizations and [2+2] cycloaddns. of chalcone functions in the polymers and the model compd. were examd. The effects of the spacer groups on the photoresponse of the chalcone moieties are discussed. .
