Polyacrylamide plastic

Acrylic textile fibers are primarily polymers of acrylonitrile. It is copolymerized with styrene and butadiene to make moldable plastics known as SA and ABS resins, respectively. Solutia and others electrolytically dimerize it to adiponitrile, a compound used to make a nylon intermediate. Reaction with water produces a chemical (acrylamide), which is an intermediate for the production of polyacrylamide used in water treatment and oil recovery. 

Y. T. Kalashnikov. Lubricant-sealer for profiled joints of casing pipes— contains soap plastic lubricant, polyacrylamide or carboxymethyl cellulose and additionally gypsum or cement powder, to increase sealing rate. Patent RU 2007438-C, 1994. 

The first pH sensor was developed at NIH (Bethesda, Maryland) and made use of phenol red as acid-base indicator, covalently bound to polyacrylamide microspheres10 such microspheres are contained inside a cellulose dialysis tubing (internal diameter 0.3 mm) connected to a 250 pm plastic fibre (Figure 2). The probe was inserted into either the tissue or the... 

Sodium bicarbonate reagent - dissolve 420 g sodium bicarbonate (sodium hydrogen carbonate) in water, add 50 ml of the polyacrylamide solution and dilute to 10 I. Add approximately 50% m/m sodium hydroxide solution, stirring with a glass rod, until the pH meter reading is steady at 8.50 at 20°C (a plastic Pasteur pipette is useful for dropwise addition approaching the required pH). 

Materials commonly use as solid supports include polystyrene, polyvinyl, nylon, glass, nitrocellulose, silica, polyacrylamide, or polystyrene beads. Separation of the bound from the free reagents can be achieved through either filtration for particulate solid supports such as agarose, polyacrylamide, and polystyrene beads, or centrifugation. For disposable forms of solid supports such as multiwell plates, plastic tubes, cuvettes, balls, and dipsticks, separation can be performed through simple rinsing steps.

Figure B3.2.2 Electroblotting with a tank transfer unit. The polyacrylamide gel containing the protein(s) to be transferred is placed on the smooth side of the polyethylene sheet (or filter paper sheets) and covered with the PVDF membrane and then a single sheet of filter paper. This stack is sandwiched between two fiber pads and secured in the plastic gel holder cassette. The assembled cassette is then placed in a tank containing transfer buffer. For transfer of negatively charged protein, the membrane is positioned on the anode side of the gel. Charged proteins are transferred electrophoretically from the gel onto the membrane.

The most common configuration for analytical IEF is the horizontal polyacrylamide slab gel. Gels are cast on glass plates or specially treated plastic sheets with one exposed face. They are placed on cooling platforms and run with the exposed gel face upward. Electrolyte strips, saturated with 1 N phosphoric acid at the anode and 1 N sodium hydroxide at the cathode, are placed directly on the exposed surface of the IEF gel. Contact between the...

Polymeric macromoleculcs of types V-VII are needed for applications requiring enhanced molecular siite (see also Chap. III). Thus, linear polymers of type V are prepared by Mannich polymerization or from bis-Mannich bases by exchange reaction, for example, with bis-thiols, as in the case of poly(ketosulfide) 501, which is useful as a high-molecular-weight antioxidant in the processing of plastics.Macromolecules of type VI are generated by the functionalization of polymers, as shown by 502, which is obtained by aminomethylation of polyacrylamide and used as flocculant in water treatment." - ... 

Mix proteins, peptide-conjugates, or eluates from polyacrylamide gels in PBS 1 1 with adjuvant (FCA for the first immunization, subsequently with FIA) in a capped plastic tube (LP3, Bijou or 30 mL universal) by vortexing until a stable emulsion is formed (see also this vol.. Chapter 1). Check that phase separation does not occur on standing at 4°C for >2 h. Alternatively, allow a drop to fall from a Pasteur pipet onto a water surface the drop should contract and remain as a droplet and not disperse.
