Synthesis of a graft polymer in“one-step”by radical/cationic transformation polymerization
关键字：One-step，Graft polymer，Transformation polymerizati
This article reports a new“one-step”synthesis of graft polymers based on the radical/cationic transformation polymerization. Using the synthetic method proposed, a graft polymer (PVAc-g-[P(AN-r-BVE)-b-PCHO]) consisting of a partly hydrolyzed poly(vinyl ...

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...
