The water-soluble tripolymer of maleic anhydride(MA), sodium allylsufonate(SAS)and acrylamide(AM) was prepared with water as solvent and persulfate as initiator.
The high molecular weight impurities in cephalosporins are the sensibilisinogen causing tacho-anaphylactic reaction and the emphasis in pharmaceutical analytical studies.
Interpolymer complexes can be formed by two polymers through hydrogen bond or electrostatic force include hydrogen complexes and polyelectrolyte complexes.
Humic acid is a kind of organic matter with high molecular quantity and satisfactory biological activity, and there are abundant humic acid in airslake-coal.
Two different kinds of palladium complexes of nitrogen containing polymere havebeen prepared and their catalytic actions for p -nitro -methyl benzfene have been invertigeted.
A numerical model of polymer debinding in PIM is proposed, the stress distribution in the greenware is analyzed and the process parameters is discussed.
The author outlines the type, characteristics of coagulant popularly used; especialy discusses the application conditions and extents of polyacrylamide, polyiron sulfate and poly alum.
In this paper, the new chelating resin (PSIM) with a polythioether backbone bearing imidazole group is first synthesized by the reaction between polychloromethylthiirane and imidazole.
Chlorinated Polyethylene (CPE) is a macromolecule and orderless chloride of Polyethylene.It is a rubber shaped plastic, which after being vulcanization treatment, can turn into elastic rubber.
Chloroamine T oxidization resin, a new solid phase agent for iodination is prepared.The synthesis conditions are studied and the oxidation reduction properties of the resin are determined.
The result shows that it can effectively prevent the flammable liquid volatilizezing from the solid alcohol fuel by coating polymer on surface for the environment - friendly purpose.
Instead, their test tube was filled with some "contaminant": A high molecular weight polymer they would soon identify as the first actin-binding protein, later called filamin A.
Scientists at Germany's Leibniz Institute of Polymer Research created this technology in 2015, in the hopes of inventing car and truck tires that can fix themselves.
As well as their security features, polymer banknotes are also cleaner and they last two and a half times longer than paper notes, which offsets the increase in cost.
Velev and Ph.D. student Alexander Richter discovered that silver-based nanoparticles can be replaced with non-harmful nanoparticles based on an organic polymer called lignin, naturally found in most plants.
In addition, we're able to throw the entire polymer chemistry textbook at this, and we're able to design chemistries that can give rise to the properties you really want in a 3D-printed object.
