CAS NO: 1561-92-8
Molecular Formula: CH2C(CH3)CH2SO3Na
Structural Formula:
Molecular Weight: 158.156
Applications:
1. As a high-performance water reducer—monomer raw material for polycarboxylate concrete water reducers, providing essential and stable sulfonic acid groups. With the rapid development of safe, environmentally friendly, and efficient polycarboxylate water reducers, our sodium methallyl sulfonate product is increasingly favored by manufacturers.
2. As a third monomer in acrylonitrile polymerization, primarily used to improve the dyeability, heat resistance, hand feel, and spinnability of acrylic fibers. It can also synthesize temperature-resistant and salt-resistant copolymer oil displacement agents. Additionally, it finds applications in water treatment, pigment solution additives, carbon pore creation, plastic powder molding, powder coating, and more.
