Thermoresponsive phase transitions of PLA-block-PEO-block-PLA triblock stereo-copolymers in aqueous solution
Macromolecular Research - Tập 10 - Trang 359-364 - 2002
Hyung Tak Lee, Doo Sung Lee
A series of PLA-PEO-PLA triblock stereo-copolymers with varying PLA/PEO and L-/DL-LA ratios were synthesized via ring opening polymerizations. Aqueous solutions of these copolymers undergo thermo-responsive phase transitions as the temperature monotonically increases. Further study shows that there is a critical gel concentration (CGC), and also lower and upper critical gel temperatures (CGTs), at...... hiện toàn bộ
Preparation of polyesteramides based on aliphatic amine-containing phenol derivatives via interfacial polymerization
Macromolecular Research - Tập 11 - Trang 328-333 - 2003
Byung-Hoon Kim, Chil-Won Lee, Myoung-Seon Gong
A series of polyesteramides with randomly introduced ester/amide group ratio of 50/50 were newly synthesized by reacting terephthaloyl chloride, isophthaloyl chloride and sebacoyl chloride with tyramine and tyrosine. The polymerization was carried out by interfacial polymerization in two phase solvent systems, which gave various polyesteramides with moderate molecular weights in good yields. The c...... hiện toàn bộ

Cytotoxicity and In Vivo Biosafety Studies of the Poly(alkylphenol) Derivatives as Vulcanizing Agents
Macromolecular Research - Tập 27 - Trang 1081-1088 - 2019
Yoon Ju Song, Joon Woo Chon, Hyuk Yoo, Jin Hwan Kim, Dong June Chung
In this research, studies of mechanical properties, in vitro cytotoxicity, and in vivo biological safety of compounded rubber samples that contained various novel vulcanizing agents derived from poly(alkylphenol) disulfide were investigated to evaluate the possibility of clinical application. From tensile test results, every compounded rubber sample showed improved elongation properties compared t...... hiện toàn bộ
Polymerization with Borane Chemistry. Tributylborane/p-Quinone System as a New Method of Reversible-Deactivation Radical Copolymerization for Styrene and Methyl Acrylate
Macromolecular Research - Tập 28 - Trang 851-860 - 2020
Dmitrii Ludin, Yulia Voitovich, Evgenia Salomatina, Yulia Kuznetsova, Ivan Grishin, Igor Fedushkin, Sergey Zaitsev
We report a reversible-deactivation radical copolymerization of styrene and methyl acrylate in the presence of tributylborane and different p-quinones. p-Quinones, such as 1,4-naphthoquinone, 2,3-dimethyl-1,4-benzoquinone, 2,5-ditert-1,4-butylbenzoquinone, and duroquinone, with addition of a catalytic amount of tributylborane, allow for the control over styrene/methyl acrylate copolymerization.

Design of h-BN-Filled Cyanate/Epoxy Thermal Conductive Composite with Stable Dielectric Properties
Macromolecular Research - Tập 26 - Trang 602-608 - 2018
Yangxue Lei, Zengmao Han, Dengxun Ren, Hai Pan, Mingzhen Xu, Xiaobo Liu
The thermal conductive cyanate ester/epoxy (CE/AG80) composites with hexagonal boron nitride (h-BN) reinforced were manufactured and investigated. The low and stable dielectric constant/loss of the composites with respect to both frequency (500 Hz-100 kHz) and temperature (50-350 °C) were discussed as functions of the content of h-BN. It was found that the low and stable dielectric constant/ loss ...... hiện toàn bộ

Structure and properties of polyimide (BTDA-TDI/MDI co-polyimide) fibers obtained by wet-spinning
Macromolecular Research - Tập 19 - Trang 645-653 - 2011
Hong Bing Xiang, Zhong Huang, Li Qi Liu, Lei Chen, Jing Zhu, Zu Ming Hu, Jun Rong Yu
BTDA-TDI/MDI (P84, synthesized by the condensation of 2,4-diisocyanato-1-methylbenzene and 1,1′-methylenebis(4-isocyanatobenzene) with 5,5′-carbonylbis(l,3-isobenzofurandione)) co-polyimide fibers were prepared by wet-spinning. The basic spinning conditions were found from the studies of dope viscosity, ternary phase diagrams, coagulation value, and precipitation value. The effect of the coagulati...... hiện toàn bộ
