What is 2-METHYL-2-PROPENE-1-SULFONIC ACID SODIUM SALT CAS 1561-92-8?
The unique value of sodium methacrylate mainly stems from its "bifunctional" molecular structure:
Hydrophilic groups: The sulfonic acid group at the molecular end (-SO₃Na) endows it with excellent water solubility and extremely strong hydrophilicity.
Reaction site: The olefin double bond in the molecule enables it to participate in free radical copolymerization reactions, thereby allowing it to be grafted onto the polymer chain.
This structure enables it to play a crucial role in various applications, such as introducing hydrophilic groups or acting as a molecular weight regulator. It has a relatively high melting point, usually exceeding 300°C, and is relatively stable at room temperature, but it should be avoided from coming into contact with oxides.
