Hydrazide functionalized 2-hydroxybenzophenone ultraviolet light and heat stabilizers and derivatives are disclosed having the general formula: ##STR1## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, X, Y, Z, all substituents thereof, and n are set forth in the Summary of the Invention. Y--N(R.sup.6)--Z is the hydrazide or derivative group and --X--R.sup.5 -- links the hydrazide group to an aromatic nucleus of the optionally substituted benzophenone group. Derivatives are, for example, acyl hydrazides, diacyl hydrazides (including imides), hydrazones and alkyl hydrazides. The compounds are useful as ultraviolet light absorbers and heat stabilizers for plastics.
揭示了具有通用公式的酰肼功能化2-羟基苯基酮紫外光和热稳定剂及衍生物:##STR1## 其中R.sup.1、R.sup.2、R.sup.3、R.sup.4、R.sup.5、R.sup.6、X、Y、Z、所有它们的取代基以及n在发明摘要中列出。 Y-N(R.sup.6)-Z是酰肼或衍生物基团,而-X-R.sup.5-将酰肼基团与可选择取代的苯基酮基团的芳香核连接起来。 衍生物包括酰肼、二酰肼(包括亚酰胺)、酰肼醛和烷基酰肼等。 这些化合物可用作塑料的紫外光吸收剂和热稳定剂。
