Polymer Bulletin 2012, 68, 69-83
关键字：Poly (ε-caprolactone), Poly(acrylic acid), PH-responsive,
The pH-responsive amphiphilic PCL-b-PAA was synthesized via ATRP of Methoxymethlacrylate (MOMA), a hemiketal ester of acrylic acid, with PCL-Br as macroinitiator, and followed by the hydrolysis of PMOMA segment under a mild condition without the degradability of PCL segment. 1H NMR, GPC,and FTIR were used to characterize the structure of polymers. Subsequently，the self-assembly of PCL-b-PAA was i...

Statics and dynamics of single polymer chains confined in nanochannels: flexibility matters
The configurations and dynamics of a flexible chain confined in a tube were described quite some time agoby de Gennes [1–3] and Odijk [4] (Fig. 1). Emerging genomics technologies such as DNA barcoding [5, 6] havebrought ...

Theory of nonlinear creep under large deformation in polymer glasses
Creep is defined by the time dependence of strain at constant stress. An ideal one-step creep experiment is theresponse to a fixed stress turned on at time zero. At low stress, the typical ideal creep curve of polym...

Spinodal-assistant growing dynamics of critical nucleus in polymer blends
In metastable system, nonclassical critical nucleus is not a drop of stable phase in core wrapped with a sharp interface, but a diffuse structure depending on the metastability.

APPLICATION OF A NUMERICAL MODEL FOR PREDICTION OF PYROLYSIS OF POLYMER NANOCOMPOSITES IN THE CONE CALORIMETER
It is well known that the formation of a surface layer, during combustion of polymer nanocomposites in the cone calorimeter, is responsible for the reduced heat release rate. In a previous study (Zhang et al., 2008), the...
