Viscosity Dependence of the Rotational Reorientation of Rhodamine B in Mono- and Poly-alcohols
Viscosity Dependence Rotational Reorientation Rhodamine B Mono-and Poly-alcohols
2016/5/20
Rotational reorientationtimes (TROT)were obtained for rhodamine B in a series of n-alcoholsand polyalcohols of varying viscositiesby a transient grating technique. The general trend of the Debye-Stoke...
通过Hofmann降解反应制备对铜离子(Cu2+ ) 具有高效吸附作用的两性聚合物—聚(丙烯酰胺／2-丙烯酰胺基-2-甲基丙磺酸／乙烯胺)(Poly(AM／AMPS／VAm))。首先以AM和AMPS为单体,通过反相乳液聚合法制备了Poly(AM／AMPS) 反相乳液,然后在反相乳液中通过Hofmann降解反应将Poly(AM／AMPS) 的部分酰胺基转变为氨基,得到两性聚合物Poly(AM／AMP...
Superabsorbency, pH-Sensitivity and Swelling Kinetics of Partially Hydrolyzed Chitosan-g-poly(Acrylamide) Hydrogels
Chitosan polyacrylamide hydrogel superabsorbent pH-reversibility swelling behavior
2010/4/19
Acrylamide (AAm) monomer was directly grafted onto chitosan using ammonium persulfate (APS) as an initiator and methylenebisacrylamide (MBA) as a crosslinking agent under an inert atmosphere. Two fact...
Electrorheological Properties of Suspensions Prepared from Poly(Li-tert-butyl methacrylate) Ionomer
Electorheological fluids poly(tert-butylmethacrylate) ionomer colloidal dispersions
2010/4/20
The synthesis, characterisation and partial hydrolysis of poly(tert-butylmethacrylate), (PTBMA), and the electrorheological (ER) properties of its suspensions were investigated. The polymer was synthe...
