Potassium acrylate

Multi-polymer Materials. The literature for multi-polymer materials is extensive but is less than that for blends and grafts composed of two polymers. A ternary graft copolymer, semi-IPN is described by Rogers and Ostler (43, 44) an original crosslinked polyethylene graft-poly-(potassium acrylate) was swelled with styrene and radiation polmerized. The authors comment that most of the grafting of polymer 3 was on polymer 2, the poly (potassium acrylate). This reaction sequence can be described ...

To a single-necked round-bottomed flask (250 mL) equipped with a magnetic stirrer bar, add potassium acrylate (16.5 g, 0.15 mol), cholesteryl 11-bromoundecanoate (31.7 g, 0.05 mol) and 2,5-di-fert-butylcresol (0.75 g, 3.4 mmol) and dissolve in dimethylformamide.

Dimethyl-l,4-phenylene ether Acrylic acid-c<3-t-butyl acrylate-co-potassium acrylate-c<9-styrene Single Tg II had 1.53 mol% butyl acrylate, 2.14 mol% acrylic acid, and 0.52 mol% potassium acrylate Leung et al. (2001)... 

The kinetic data from this experiment is shown in Fig. 3.1.7, resulting in the RlO-1 product (Section 3.1.4.2). Its GPC trace is shown in Fig. 3.1.11, which indicates a material with a relatively high molecular weight and a reasonable PDI of 1.97. When the reactor product was coagulated in water with KOH, the coagulum can be drawn into a fibrous material. This is probably due to the development of microcrystalline domains of potassium acrylate in the polymer, as evidenced by a melting transition at 47°C. 

The polymerization of potassium acrylate proceeded more rapidly than that of any of the monomers studied in this work. At 0 C, potassium acrylate polymerized more rapidly than lithium acrylate at lOPC and sodium acrylate at 120 C. 

The reaction rates of all the acrylates decay rapidly at low conversions. The chain length of poly(potassium acrylate) is one order of magnitude greater than that of poly (lithium acrylate). 

Hydrogen- and deuterium-atom bombardment have been used to initiate the polymerization of barium methacrylate dihydrate. The process is said to be initiated by the diffusion of hydrogen atoms in solid-state barium methacrylate dihydrate. By this method, large amounts of polymer form very rapidly, unlike in polymerizations initiated by y-radiation [112]. y-Radiation has been used in the solid-state polymerization of potassium acrylate, calcium acrylate, barium acrylate, and uranyl acrylate [113].
