morphology control of thermoplastics toughened thermosets by phase separation approach
关键字：polymerization induced phase separation, thermosets，thermoplastics, time and temperature dependency，morphology
the phase separations of thermoplastics (polyether ketone, polyether sulphone, polyether imide) in thermosets (epoxy, cyanate ester, bismaleimide) during curing process were studied using rheology, om (optical microscope) and dsc (differential scanni...

Researches on the technique of reactive extrusion for the polymerization of block copolymers and the effect of the process control on the molecule building
关键字：Reactive extrusion, Styrene, Diene, Multiblock, Copolymer
A novel multi-block copolymers of styrene (St) and diene (D) (butadiene or isoprene ) were synthesized by one step bulk polymerization by means of the closely intermeshingtwin-screw extruder as the reactor, the mixer of St an...

Effective Morphology Control in an Immiscible Crystalline/Crystalline Blend by Artificially Selected Viscoelastic Phase Separation Pathways
关键字：Blend, Viescoelastic phase separation, crystallization, Morphology
We investigated the interplay between viscoelastic phase separation (VPS) and crystallization in a dynamically asymmetric crystalline/crystalline polymer blend
system of poly(butylene succinate) (PBS)/poly(ethylene oxide) (PEO). The dynamic asymmetry came from the large molecular weight difference between the slow relaxing PEO and the fast relaxing PBS molecules. The evolution of networklike struc...

CMPs with core-shell structure: a simple strategy to control light-emitting properties of π-conjugated systems
关键字：three-dimensional polymer / photoluminescence / porous / optoelectronic property
We have designed and synthesized a series of conjugated microporous polymers (CMPs) based on two kinds of different core building blocks by Suzuki coupling polymerization. These networks is both microporous and highly luminescent. The&...
