Abstract

This paper reports on divalent europium complexes with poly(methacrylate containing crown ether structure)s, poly(crown ether)s, prepared and their fluorescence properties studied. The polymers used were poly(15-crown-5-methyl methacrylate) (PMA15C5), copoly(15- crown-5-methyl methacrylate-X) (copoly(MA15C5-X)); (X = MMA, EMA, BMA, 2-methoxyethyl methacrylate (MAGI) 3,6,9,12,15- pentaoxahexadecyl methacrylate (MAG5)), poly(18-crown-6- methyl methacrylate) (PMA18C6), and copoly(18-crown-6-methyl methacrylate-MMA) (copoly(MA18C6-MMA)), which were obtained by bulk polymerization. The fluorescence properties of Eu{sup 2+} polymers activated by complexing Eu{sup 2+} ions with crown ether groups were measured in powder form. The Eu{sup 2+}-poly (crown ether)s irradiated by UV light generally gave blue bright emission in the region of 420-465 nm. It was Eu{sup 2+}-copoly(Ma15C5-X); (X = MMA, EMA, and MAG1) that showed the largest emission intensity among the Eu{sup 2+} polymers, and its emission intensity was ca. 20% of that for CaWO{sub 4}:Pb (NBS1026) whose quantum efficiency is about 76%. The intensities of emission for the Eu{sup 2+} polymers containing 15-crown-5 were much larger than that for the ones containing 18-crown-6.

Hairy nanoparticles by atom transfer radical polymerization in miniemulsion

Journal Article Wang, Yi; Matyjaszewski, Krzysztof - Reactive and Functional Polymers

Polymer nanoparticles with various architectures and functionalities are promising materials in numerous fields. Miniemulsion polymerization is one of the suitable pathways to prepare polymer nanoparticles since each droplet could act as a “nanoreactor”. A “smart” atom transfer radical polymerization (ATRP) catalytic system comprising Cu-TPMA/DS^– (TPMA = tris(2-pyridylmethyl)amine, DS^–= dodecyl sulfate anion) ion pair catalyst was efficiently applied in miniemulsion ATRP at low catalyst concentrations. Herein, hairy nanoparticles consisting of hydrophobic poly(n-butyl methacrylate) (P(BMA/EGDMA), EGDMA = ethylene glycol dimethacrylate) network “core” and hydrophilic oligo(ethylene oxide) methyl ether methacrylate (OEOMA) chains as “hair” were prepared by miniemulsion ATRP and a successive chainmore »« less

Radiation degradation behavior of chlorine-containing vinyl copolymers. Search for improved electron-beam resists

Journal Article Helbert, J; Poindexter, E; Pittman, Jr, C; ... - Polym. Eng. Sci.; (United States)

Vinyl copolymers with high radiation degradation sensitivity have been synthesized by copolymerizing vinylidene chloride (VDC), CH/sub 2/ = CCl/sub 2/, with methyl methacrylate (MMA), methacrylonitrile, methyl ..cap alpha..-chloroacrylate, and dimethyl itaconate using emulsion techniques. In addition, copolymers of methyl ..cap alpha..-chloroacrylate with methyl methacrylate and poly(..cap alpha..-chloroacrylonitrile) were studied. Introduction of vinylidene chloride into methyl methacrylate polymers caused a sharp increase in G/sub s/ even at relatively low VDC incorporation. Upon 29% VDC incorporation, the G/sub s/ value increased from 1.3 (homopolymer of MMA) to 3.4. G/sub s/ was found to be a linear function of copolymer content for severalmore »« less

Synthesis and evaluation of cyclic olefin sulfone copolymers and terpolymers as electron beam resists

Journal Article Gipstein, E; Moreau, W; Chiu, G; ... - J. Appl. Polym. Sci.; (United States)

Poly(cyclopentene sulfone) (PCPS) and poly(bicycloheptene sulfone) (PBCHS) copolymers have been evaluated as potential positive electron beam resists which have good thermal properties and which show high sensitivity to ionizing radiation. It was found that thin copolymer films could be processed as resists but that films greater than 3000 A thick cracked in the solvents used to dissolve the radiation-exposed regions. Films from low molecular weight polymer fractions cracked less in solvents, but higher radiation doses were required to offset the reduced sensitivity. This resulted in the formation of intractable residues in the exposed regions which appear to be crosslinked polymer.more »« less

Synthesis and radiation degradation of vinyl polymers with fluorine: search for improved lithographic resists. [Gamma rays]

Journal Article Pittman, Jr, C; Chen, C; Ueda, M; ... - J. Polym. Sci., Polym. Chem. Ed.; (United States)

Homopolymers of methyl ..cap alpha..-fluoroacrylate (MFA), trifluoroethyl methacrylate (TFEM), and hexafluoroisopropyl methacrylate (HFIM) were prepared, as were their methyl methacrylate (MMA) copolymers. Copolymers of vinylidene fluoride (VDF) and chlorotrifluoroethylene (CTFE) with MMA were also prepared. The radiation susceptibilities of these polymers were measured by the /sup 60/Co ..gamma..-irradiation method, in which molecular weights were measured by membrane osmometry and gel permeation chromatography (GPC). All the copolymers degraded by predominant chain scission except poly(methyl ..cap alpha..-fluoroacrylate), (PMFA), which crosslinks even at low doses (ca. 1 Mrad). The G/sub s/-G/sub x/ and G/sub s/ values of the chain scissioning polymers and copolymersmore »« less

Optically-based array sensors for selective in situ analysis of tank waste. 1998 annual progress report

Technical Report Brown, G; Dabestani, R; Bonnesen, P; ...

'The objective of this research program is to conduct the fundamental research necessary to develop an array of chemically selective sensors, based on highly selective molecular recognition agents and highly sensitive fluorescence and/or phosphorescence techniques, that can be coupled to fiber optics for remote analytical applications. These sensors will be of great value to DOE for the safe and cost-effective in situ characterization of high level waste tanks. Characterization of high level tank waste currently entails obtaining and analyzing core samples at the cost of about $1 million per sample. The ability to detect and measure specific chemicals and radionuclidesmore »« less
