Polymerizable UV stabilizers from isocyanatoalkyl esters of unsaturated carboxylic acids. |
摘要 |
<p>An addition polymerizable UV stabilizer is prepared by reacting an isocyanatoalkyl ester of an addition polymerizable carboxylic acid (such as 2-isocyanatoethyl methacrylate) with an UV stabilization functionality bearing an active hydrogen moiety which is reactive with the isocyanate (such as 2-hydroxy-4-(2-hydroxyethoxy)benzophenone).</p> |
