There are some commonly used reagents like 93911-23-0 in this article.; Beijing Research Institute of Chemical Engineering, China Petrochemical Co., Ltd., Peop. Rep. China). Faming Zhuanli Shenqing Gongkai Shuomingshu CN 1454906 A 12 Nov 2003, 15 pp. (Chinese). (People's Republic of China). CODEN: CNXXEV. CLASS: ICM: C08F010-00. ICS: C08F004-645. APPLICATION: CN 2002-116981 29 Apr 2002. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) The solid catalyst component is composed of Mg compd., Ti compd., and electron donor I where R1 and/or R2 = C1-20 alkyl, cycloalkyl, aryl, alkylaryl, or arylalkyl; R3 and/or R4 = H, or C1-20 alkyl, cycloalkyl, aryl, alkylaryl, or arylalkyl; and R and/or R' = H, C1-6 alkyl, alkoxy, ester group, or R + R' = a ring. Thus, 1,2-dimethoxyacenaphthylene was prepd. from 1,2-acenaphthenediol and Me iodide, 1.7 g of which was mixed with MgCl2 4.8 g and TiCl4 56 mL to form a catalyst for propylene polymn. at 70°to give a product having isotacticity 97.64 and melting index 2.83 g/10 min. .

Structure and photophysical behaviors of Langmuir-Blodgett (LB) films containing copolymers of diethyl fumarate with vinylcarbazole and acenaphthylene: Structure and photophysical behaviors of Langmuir-Blodgett (LB) films containing copolymers of diethyl fumarate with vinylcarbazole and acenaphthylene. Murakata, Tadahiro; Miyashita, Tokuji; Matsuda, Minoru (Chem. Res. Inst. Non-aqueous Solutions, Tohoku Univ., Sendai 980, Japan). Macromolecules, 21(9), 2730-3 (English) 1988. CODEN: MAMOBX. ISSN: 0024-9297. DOCUMENT TYPE: Journal CA Section: 36 (Physical Properties of Synthetic High Polymers) Acenaphthylene-di-Et fumarate copolymer and di-Et fumarate-N-vinylcarbazole alternating copolymer gave stable monolayer films when they were mixed with stearic acid, though in the mixed monolayer films phase sepn. into the copolymer and stearic acid phase occurred. The monolayer films could be transferred onto solid supports successively by the Langmuir-Blodgett (LB) method. In these multilayer LB films, excited energy-transfer and photoinduced electron-transfer processes were studied by adding amphiphilic dyes as acceptor mols., and the efficiencies of the processes were discussed.
