Well‐defined thermoresponsive dendritic polyamide/poly(N‐vinylcaprolactam) block copolymers
03-05-2013 | Yunmei Bi, Caixian Yan, Lidong Shao, Yufei Wang, Yongcui Ma, Gang Tang, Journal of Polymer Science Part A: Polymer Chemistry, 2013
ABSTRACT The first‐ and second‐generation well‐defined thermoresponsive amphiphilic linear–dendritic diblock copolymers based on hydrophilic linear poly(N‐vinylcaprolactam) and hydrophobic dendritic aromatic polyamide have been synthesized via reversible addition fragmentation chain ...
Poly (N‐isopropylacrylamide) microgel‐based assemblies
24-04-2013 | Liang Hu, Avijeet K. Sarker, Molla R. Islam, Xue Li, Zhenzhen Lu, Michael J. Serpe, Journal of Polymer Science Part A: Polymer Chemistry, 2013
ABSTRACT Thermally responsive poly (N‐isopropylacrylamide) (pNIPAm)‐based hydrogel particles (microgels) have been extensively studied over past few decades. We, and others, have found that assemblies of these microgels exhibit unique properties that make them useful such as nonfouling ...
Stimuli‐responsive star polymers
22-04-2013 | Dirk Kuckling, Agnes Wycisk, Journal of Polymer Science Part A: Polymer Chemistry, 2013
ABSTRACT Stimuli‐responsive star polymers gain more and more interest over the last decades due to their unique properties compared to their linear counterparts. The branched structure for instance has influence on the responsive behavior of these polymers. This review offers an overview ...
Amphiphilic diblock copolymers based on poly(2‐ethyl‐2‐oxazoline) and poly(4‐substituted‐ε‐caprolactone): Synthesis, characterization, and cellular uptake
22-04-2013 | Kang‐Yu Peng, Shiu‐Wei Wang, Ren‐Shen Lee, Journal of Polymer Science Part A: Polymer Chemistry, 2013
ABSTRACT Amphiphilic diblock copolymers with various block compositions were synthesized on poly(2‐ethyl‐2‐oxazoline) (PEtOz) as a hydrophilic block and poly(4‐methyl‐ε‐caprolactone) (PMCL) or poly(4‐phenyl‐ε‐caprolactone) (PBCL) as a hydrophobic block. These PEtOz‐b‐PMCL and PEtOz‐b‐PBCL ...
Synthesis of poly(ethylene glycol)‐based hydrogels and its swelling/shrinking properties responsive for molecular recognitions
19-04-2013 | Yuichi Tominaga, Takuya Kubo, Kenji Sueyoshi, Ken Hosoya, Koji Otsuka, Journal of Polymer Science Part A: Polymer Chemistry, 2013
ABSTRACT To synthesize the novel molecular‐ and pH‐stimulus‐responsive hydrogel, we prepared poly(ethylene glycol)‐based hydrogel containing ionic groups. We evaluated the fundamental swelling/shrinking properties of the hydrogels synthesized by various conditions. Decreasing the ...
Facile synthesis and electro‐optic activities of new polycarbonates containing tricyanofuran‐based nonlinear optical chromophores
02-04-2013 | Guowei Deng, Shuhui Bo, Tingting Zhou, Heyan Huang, Jieyun Wu, Jialei Liu, Xinhou Liu, Zhen Zhen, Ling Qiu, Journal of Polymer Science Part A: Polymer Chemistry, 2013
ABSTRACT Two series of novel electro‐optic (EO) polycarbonates containing two different kinds of nonlinear optical (NLO) chromophores with tricyanofurane (TCF) electron acceptor have been successfully prepared through the facile polycondensation between diol NLO chromophore and bisphenol ...
Hydrophilic CO2‐based biodegradable polycarbonates: Synthesis and rapid thermo‐responsive behavior
02-04-2013 | Lin Gu, Yusheng Qin, Yonggang Gao, Xianhong Wang, Fosong Wang, Journal of Polymer Science Part A: Polymer Chemistry, 2013
ABSTRACT Common CO2‐based biodegradable polycarbonates like poly(propylene carbonate) or poly(cyclohexene carbonate) are generally hydrophobic, leading to slow biodegradation rate and poor cell adhesion, which limit their applications in the biomedical field. Here hydrophilic ...
Synthesis and characterization of resorcinarene‐centered amphiphilic A8B4 miktoarm star copolymers based on poly(ε‐caprolactone) and poly(ethylene glycol) by combination of CROP and “click” chemistry
01-04-2013 | Chen Gao, Ying Wang, Pengfei Gou, Xia Cai, Xiaodong Li, Weipu Zhu, Zhiquan Shen, Journal of Polymer Science Part A: Polymer Chemistry, 2013
ABSTRACT Well‐defined amphiphilic A8B4 miktoarm star copolymers with eight poly(ethylene glycol) chains and four poly(ε‐caprolactone) arms (R‐8PEG‐4PCL) were prepared using “click” reaction strategy and controlled ring‐opening polymerization (CROP). First, multi‐functional precursor ...
One‐pot synthesis of composite microspheres with core‐shell structure
29-03-2013 | Yi Gong, Qing Lin Liu, Ai Mei Zhu, Qiu Gen Zhang, Journal of Polymer Science Part A: Polymer Chemistry, 2013
ABSTRACT One‐pot synthesis of thermoresponsive magnetic composite microspheres with a poly(N‐isopropylacrylamide) (PNIPAM) shell and a Fe3O4 core is demonstrated. Temperature sensitivity of PNIPAM was adopted to design the novel synthesis pathway. The as‐prepared composite microspheres ...
Synthesis of imidazole‐terminated hyperbranched polymers with POSS‐branching points and their pH responsive and coordination properties
29-03-2013 | Yasuyuki Irie, Kensuke Naka, Journal of Polymer Science Part A: Polymer Chemistry, 2013
ABSTRACT An imidazole‐terminated hyperbranched polymer with octafunctional POSS branching units denoted as POSS‐HYPAM‐Im was prepared by the polymerization of excess amounts of tris(2‐aminoethyl)amine with the first‐generation methyl ester‐terminated POSS‐core poly(amidoamine)‐typed ...
