| 摘要 |
<p>Novel benzotriazoles (BZT) compounds are disclosed which are useful as high temperature stable monomeric benzotriazoles, polymerizable benzotriazoles, and polymers containing the benzotriazole functionality useful as ultraviolet light stabilizers, metal chelaters. Products of the present invention are derivatives of 4-hydroxyacetophenone benzotriazole (4-HAP-BZT), and 4-hydroxyphenylmethyl carbinol benzotriazole (4-HPMC-BZT).</p> |
