ATBS/AMPS is supplied in a granule or powder form. Depending on the polymerization molecular weight sought and the performance characteristics desired, ATBS/AMPS is offered in 3 grades: 2401, 2404 and 2406.
An overview of AMPS Monomer:
Acrylamide tertiary-butyl sulfonic acid (CAS 15214-89-8) is a very unique versatile vinyl compound that has a sulphonic group. Its uses are widely found in the production of polymers, textiles, flocculants, dispersants, scale control agents and well-additives.
AMPS monomer is a reactive, hydrophilic, sulphonic acid acrylic monomer used to alter the chemical properties of a large variety of anionic polymers. Acrylamide tertiary-butyl sulfonic acid is prepared by the reaction of acrylonitrile and isobutylene in the presence of sulfuric acid and water.
The ATBS monomer allows the manufacturing of high-quality polymers for application in a wide range of consumer and industrial products. The AMPS monomer at Vinati Organics Ltd is organic, high in productivity and performance and available in both granules and liquid form. For ease of handling, AMPS is also offers in a 50% sodium salt solution called NaAMPS.
