performance of partially-hydrolyzed polyacrylamide in water based drilling fluids
fluid properties with constant improvement in efficiency have been noticeable as important criteria in drilling operation. the main drilling fluid properties highly depend on utilization of new polymers with high efficiency in drilling fluid composition. in this paper, the performance of a new polymer, called partially hydrolyzed polyacrylamide polymer (phpa), is studied which has recently ente...

15 صفحه اولPolyacrylamide Gel Electrophoresis
Polyacrylamide gels are typically formed by polymerization of the monomer acrylamide crosslinked to the co-monomer, N,N’-methylenebis-acrylamide, commonly called BIS. This process is a freeradical polymerization that requires an initiator, usually ammonium persulfate, and a catalyst like N,N,N’,N’-tetraethylmethylenediamine (TEMED). A distinct advantage of polyacrylamide gel systems is that by ...
متن کاملNeutral polyacrylamide gel electrophoresis.
MATERIALS 5x TBE electrophoresis buffer Polyacrylamide gels are poured and run in 0.5x or 1x TBE at low voltage (1-8 V/cm) to prevent denaturation of small fragments of DNA by Joulic heating. Other electrophoresis buffers such as 1x TAE (please see Agarose Gel Electrophoresis) can be used, but they are not as good as TBE. The gel must be run more slowly in 1x TAE, which does not provide as much...
متن کاملSynthesis of Partially Hydrolyzed Graftcopolymer Based Superabsorbent
Gellan Gum (GG) was modified with N-vinyl Formamide (NVF) through PDP/Ag + redox system initiated graft copolymerization in a thermostatic water bath at 35°C under nitrogen atmosphere. The highest percentage of grafting (186%) and the lowest homopolymer content (22.2%) were achieved through a systematic optimization of the polymerization variables, including reaction time, temperature, and conc...
