Novel supramolecular system of amphiphilic hyperbranched polymer with β-cyclodextrin and hyperbranched topography cavities: Synthesisand selective encapsulation
关键字：amphiphilic hyperbranched polymer,β-cyclodextrin
Novel supramolecular system of amphiphilic hyperbranched polymer with hyperbranched poly(bcyclodextrin)
core was designed and synthesized to accomplish a so-called selective encapsulation,
where two types of guest molecules can be encapsulated into two types of molecular cavities from bcyclodextrin
(b-CD) and topography structure of hyperbranched polymer, respectively. The double
molecular rec...

Journal of Polymer Science Part A: Polymer Chemistry 2011, 49, 5293
关键字：copolymerization, reactivity ratios, chain sequence, crystallization
A series of copolymers containing ε-caprolactone (CL) and 4-methyl-ε-cap-rolactone (MeCL) were synthesized by ring-opening polymerization (ROP) using Tin(Ⅱ)bis(2-ethylhexanoate)(Sn(Oct)2) or Novozym 435 as catalyst. The molecular structure and weight of copolymers were determined by Nuclear Magnetic Resonance (NMR) and size exclusion chromatography (SEC), respectively. Our kinetic...

Effect of the addition of hydrophobic clay on the electrochemical property of polymer electrolytes
关键字：Composite polymer electrolyte，Montmorillonite
In this study, an organoclay, ALA–MMT, was prepared by the ionic exchange reaction of montmorillonite(MMT) with 12-aminododecanoic acid (ALA). ALA–MMT was then used as a filler to prepare a series of composite polymer electrolytes&nb...

Synthesis and characterization of a novel superabsorbent polymer of N,O-carboxymethyl chitosan graft
关键字：N,O-Carboxymethyl chitosan, Superabsorbent polymer
A novel superabsorbent polymer was prepared by graft copolymerization of sodium acrylate and 1-vinyl-2-pyrrolidone onto the chain of N,O-ca-rboxymethyl chitosan. The molecular structure of the product was confirmed by FTIR. The surface morp...

The new worldview of nonlinear polymer theology: its phenomenological foundation and significance for polymer processing
we will review the discoveries in the field of nonlinear theology of entangled polymers since 2006 when it was first reported that synthetic polymers could undergo inhomogeneous shear beyond the stress overshoot during startup shear and show non-quiescent relaxation after a large step strain [1-2] In the past decade, we have attempted to develop a realistic understanding to address the follo...

On the elasticity of polymer fluids
关键字：fluid elasticity polymer fluids die swell inlet pressure drop References
It was showed in literatures that polymer fluids (as melts or solutions) which have similar viscosity but different elasticity, their theological and processing behaviors were widely divergent.The measure method and norm for fluid elasticity are not a circumstance to fluid viscosity. The physical quantities to describe of fluid elasticity in literatures were various [1-2] There are distinguishe...
