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...

Journal of Macromolecular Science, Part A: Pure and Applied Chemistry 2012 49, 124
关键字：ATRP /PCL/PDEAEMA /pH sensitivity/ ROP/self-assembly
Four-arm star block polymers consisting of hydrophobic poly(ε-caprolactone) (PCL) block and hydrophilic poly(2-(diethylamino) ethyl methacrylate)) (PDEAEMA) block were successfully synthesized by ring opening polymerization (ROP) and atom transfer radical polymerization (ATRP). Chain lengths of PDEAEMA segments were varied to obtain a series of star copolymers with different hydrophilic/hy...

Ionic Liquids for Cellulose–A Perfect Green Combination?
关键字：Ionic liquids, cellulose chemistry, sustainability
Ionic Liquids (IL), which are low melting salts of organic cations and inorganic or organic anions, often are referred to as green solvents. Negligible volatility (vapor pressure) is the main argument for backing this attribute.&n...

SELF-ASSEMBLY OF CHITOSAN-g-PEG AND a-CYCLODEXTRIN INTO HOLLOW SPHERES IN AQUEOUS SOLUTION
关键字： hollow spheres, chitosan, self-assembly, inclusion chemistry
Polymeric hollow nanospheres were prepared by self-assembly of rod-coil complexes, in which the rod-like segments were formed by inclusion a-cyclodextrins (a-CD) and grafting poly(ethylene glycol) (PEG) chains of chitosan-graft-PEG (CS-g-PEG).
