Método para inibir polimerização prematura de monômeros estirênicos, composição |
摘要 |
<p>A method for inhibiting the premature polymerization of styrenic monomers is disclosed wherein the method comprises adding to said monomers a combination of: (A) at least one inhibitor that is a sulfonic acid compound in a concentration sufficient to initiate cationic polymerization of said styrenic monomers at any point of the manufacturing or purification process and cause a resulting temperature increase; and (B) at least one amine in a concentration sufficient to reduce said cationic polymerization and said temperature increase; whereby an uncontrolled exothermic reaction between said sulfonic acid compound and said styrenic monomers will be prevented.</p> |
