Preparation of polyethylene block copolymers by a combination of postmetallocene catalysis of ethylene polymerization and atom transfer radical polymerization
Wiley - Tập 42 Số 3 - Trang 496-504 - 2004
Yoshihisa Inoue, Krzysztof Matyjaszewski
AbstractThe synthesis of block copolymers consisting of a polyethylene segment and either a poly(meth)acrylate or polystyrene segment was accomplished through the combination of postmetallocene‐mediated ethylene polymerization and subsequent atom transfer radical polymerization. A vinyl‐terminated polyethylene (number‐average molecular weight = 1800, weight‐average...... hiện toàn bộ
Biological–synthetic hybrid block copolymers: Combining the best from two worlds
Wiley - Tập 43 Số 1 - Trang 1-17 - 2005
Harm‐Anton Klok
AbstractAlthough biopolymers and synthetic polymers share many common features, each of these two classes of materials is also characterized by a distinct and very specific set of advantages and disadvantages. Combining biopolymer elements with synthetic polymers into a single macromolecular conjugate is an interesting strategy for synergetically merging the proper...... hiện toàn bộ
Hydrolyzable poly(ester‐urethane) networks from L‐lysine diisocyanate and D,L‐lactide/ϵ‐caprolactone homo‐ and copolyester triols
Wiley - Tập 32 Số 12 - Trang 2345-2363 - 1994
Robson F. Storey, Jeffrey S. Wiggins, A Puckett
AbstractBioabsorbable poly(ester‐urethane) networks were synthesized from ethyl 2,6‐diisocyanatohexanoate (L‐lysine diisocyanate) (LDI) and a series of polyester triols. LDI was synthesized by refluxing L‐lysine monohydrochloride with ethanol to form the ester, which was subsequently refluxed with 1,1,1,3,3,3‐hexamethyldisilazane to yield a silaz...... hiện toàn bộ
Influence of the bisphenol structure on the direct synthesis of sulfonated poly(arylene ether) copolymers. I
Wiley - Tập 41 Số 14 - Trang 2264-2276 - 2003
William Harrison, Feng Wang, Jeffrey B. Mecham, V. A. Bhanu, Melinda Hill, Yu Seung Kim, James E. McGrath
AbstractNew sulfonated poly(arylene ether sulfone) copolymers with high molecular weights were successfully synthesized with controlled degrees of disulfonation of up to 70 mol % via the direct copolymerization of sulfonated aromatic dihalides, aromatic dihalides, and one of four structurally distinct bisphenols. The disodium salts of the 3,3′‐disulfonated‐4,4′‐dic...... hiện toàn bộ
Rational design of polyhedral oligomeric silsesquioxane fillers for simultaneous improvements of thermomechanical properties and lowering refractive indices of polymer films
Wiley - Tập 51 Số 17 - Trang 3583-3589 - 2013
Jong‐Hwan Jeon, Kazuo Tanaka, Yoshiki Chujo
ABSTRACTWe describe here the design and synthesis of the polyhedral oligomeric silsesquioxane (POSS)‐based dual‐functional molecular fillers for simultaneously lowering refractive indices and improving thermomechanical properties of conventional polymers. We prepared the composite films with poly(methyl methacrylate) and polystyrene containing the series of the POS...... hiện toàn bộ
Synthesis and self‐assembly of tadpole‐shaped organic/inorganic hybrid poly(N‐isopropylacrylamide) containing polyhedral oligomeric silsesquioxane via RAFT polymerization
Wiley - Tập 46 Số 21 - Trang 7049-7061 - 2008
Weian Zhang, Li Liu, Xiaodong Zhuang, Xiaohui Li, Jinrui Bai, Yu Chen
AbstractAminopropylisobutyl polyhedral oligomeric silsesquioxane (POSS) was used to prepare a POSS‐containing reversible addition‐fragmentation transfer (RAFT) agent. The POSS‐containing RAFT agent was used in the RAFT polymerization of N‐isopropylacrylamide (NIPAM) to produce tadpole‐shaped organic/inorganic hybrid Poly(N... hiện toàn bộ
High-performance segmented polyurea by transesterification of diphenyl carbonates with aliphatic diamines
Wiley - Tập 52 Số 19 - Trang 2781-2790 - 2014
Wen Chen Pan, Ching Hsuan Lin, Shenghong A. Dai
The ligand effect in Ti‐mediated living radical styrene polymerizations initiated by epoxide radical ring opening. 2. Scorpionate and half‐sandwich LTiCl3 complexes
Wiley - Tập 43 Số 23 - Trang 6039-6047 - 2005
Alexandru D. Asandei, Isaac W. Moran
AbstractThe ligand effect and the reaction conditions for the living radical polymerization of styrene initiated by epoxide radical ring opening was investigated in a series of piano‐stool, Ti(IV) scorpionate and, half‐sandwich metallocenes (LTiCl3; L = Tp, Cp*, Ind and Cp, where Tp = hydrotris(pyrazol‐1‐ylborato), Cp* = pentamethylcyclopentadi...... hiện toàn bộ
Synthesis and characterization of monosubstituted and disubstituted poly(3,4‐propylenedioxythiophene) derivatives with high electrochromic contrast in the visible region
Wiley - Tập 43 Số 2 - Trang 419-428 - 2005
Sarada P. Mishra, Kothandam Krishnamoorthy, Rabindra Sahoo, Anil Kumar
AbstractMonosubstituted and disubstituted 3,4‐propylenedioxythiophenes were synthesized and polymerized by both chemical and electrochemical methods. All the monomers were characterized for their molecular structures, and the polymers were characterized for their electrochemical properties. The disubstituted derivatives showed higher contrast than the corresponding...... hiện toàn bộ
Molecular weight control of polyacrylamide with sodium formate as a chain‐transfer agent: Characterization via size exclusion chromatography/multi‐angle laser light scattering and determination of chain‐transfer constant
Wiley - Tập 41 Số 4 - Trang 560-568 - 2003
Michael J. Fevola, Roger D. Hester, Charles L. McCormick
AbstractWe discuss the synthesis and characterization of polyacrylamide (PAM) homopolymers with carefully controlled molecular weights (MWs). PAM was synthesized via free‐radical solution polymerization under conditions that yield highly linear polymer with minimal levels of hydrolysis. The MW of the PAM homopolymers was controlled by the addition of sodium formate...... hiện toàn bộ
