buy manufacture anionic polyacrylamide apam in brazil sugar,polyacrylamide (pam) is a water-soluble linear high-molecular polymer formed by free radical polymerization of acrylamide monomer. at the same time, it is also a kind of polymer water treatment flocculants, which can absorb suspended particles in the water and act as a link and bridge between the particles, so that the fine particles form relatively large flocks and accelerate the speed of
a survey on cationic polyelectrolytes and their applications
cationic polyelectrolytes are water-soluble polymers bearing positive ionic groups along the backbone or in side chains. these cationic polymers are synthesized by free radical polymerization of acrylamide and their derivatives by the copolymerization method, which includes solution, precipitation, and emulsion techniques. the mannich reaction is another important method by which the cationic
nonionic polyacrylamide (npam) with factory price.textile and dyeing industry: nonionic polyacrylamide is employed as a textile auxiliary agent. it can act as a dispersant, helping to evenly distribute dyes and pigments in textile dyeing processes. it also improves the fabric’s color fastness, prevents staining, and enhances the uniformity of dye uptake. soil conditioning and erosion control
functionalization of cationic polymers for drug delivery
gelatine is a thermally denatured collagen extracted from porcine skin or bovine bone and is commonly used for pharmaceutical and medical applications because of its biodegradability. 1–4 being categorized as a safe excipient by the us food and drug administration (fda), gelatine has shown great promise as a component of biomaterials in many medical applications. 5,6 for example, gelatine
