2 – Acrylamido–2 Methylpropane sulfonic acid applications

2 – Acrylamido–2 Methylpropane sulfonic acid as a white apparent powder, melting point 185 ℃, hardly sour, with a able hygroscopicity. Such as damp, AMPS monomer cocky polymerization can occur. Its baptize band-aid is acidity, acrid in two methyl amide, partially acrid in methanol, ethanol, baffling in acetone. Stable at allowance temperature. In aqueous solution, monomer hydrolysis acceleration is actual slow, but have to add inhibitor, to anticipate its cocky polymerization; sodium band-aid at pH greater than 9 conditions, with accomplished hydrolysis resistance; homopolymers with acceptable thermal stability. AMPS monomer can be copolymerized homopolymer, can aswell be. AMPS accession in baptize calefaction for an boilerplate of 22000 cal / mol, baptize and two DMF can be acclimated as polymerization medium.

2 – Acrylamido–2 Methylpropane sulfonic acid amalgam with acrylonitrile, isobutene, angry sulfuric acerbic as raw material, the angry sulfuric acerbic is added to the admixture of acrylonitrile and isobutylene in the attendance of assorted additives, in absolute acknowledgment to access the accomplished product. China AMPS analysis and assembly started late, AMPS advanced ambit of uses, and adopted manufacturers less, this gives Chinese assembly and development brings acceptable acceptable luck. At present the calm appliance of AMPS is absolutely weak, mainly in the oil acreage and the acreage of baptize treatment, constructed technology and adopted photograph is earlier than difference, so the artefact abstention is not high, aswell affects the after artefact applications. AMPS is the blanket industry accomplished achievement of the modifying agent, adhering and blanket abettor achievement convalescent agent. AMPS copolymer acrylic acerbic alternation anion electrophoretic acrylic or blanket the abject resin, can acutely advance the blur gloss, backbone and durability. AMPS and polyhydroxy admixture heating and melting the admixture is hot cook adhesive. AMPS and vinylidene chloride – acrylic adhering copolymer acquired water-soluble polymer coated assimilate the polyolefin film, can advance the calefaction sealing performance.
