Brief introduction

AMPS is a strong anonic water soluble sulfonic acid group, which has salt resistance, high temperature resistance, staining affinity, conductivity, ion exchange and good tolerance to second ion cations; the amide group has good hydrolysis stability, acid resistance and thermal stability; and the active double bond has additive polymerization performance, and can produce copolymers with a variety of hydrocarbon monomers.

Character

AMPS with good polymerization performance, it can homopolymerize by itself, and can also copolymerize with a variety of other monomers, and synthesize millions or even tens of millions of high relative molecular mass polymers.

Application

The copolymers of AMPS with other monomers are widely used in the fields of textile, printing and dyeing, plastics, coating, papermaking, wastewater treatment, daily chemical, leather and oilfield chemistry. AMPS used for modified monomer of acrylic fiber can significantly improve the spinnability, staining, antistatic resistance, wear resistance, whiteness and transparency; AMPS is used to prepare high water absorption resin to improve the ability of resin suction saline.
