Monomers can be mainly used as intermediates in pharmaceutical manufacturing, and can be homopolymerized or copolymerized with other monomers to form a series of polymer products. Its polymer can be used as a superior non-waking and fixing agent in textile dyeing and finishing AIDS to form film on fabrics and improve dyeing fastness. It can be used as a retention filter aid, paper coating antistatic,AKD maturation promoter in papermaking additives; In oilfield chemicals, it can be used as clay stabilizer, cationic additive of acidified fracturing fluid, etc. Its main role is electrical neutralization, adsorption, flocculation, purification, decolorization, especially as a synthetic resin modifier, given conductivity, antistatic property.
