  Novel ultraviolet absorbing compounds that are liquid in nature, are low in color (and thus permit use without the concomitant necessity of adding large amounts of other coloring agents to combat such discoloring), and are highly effective in providing protection in wavelength ranges for which previous attempts at low-color ultraviolet absorbers have failed are provided herein. Such compounds provide such excellent, inexpensive, and beneficial protection from ultraviolet exposure within various media, including, but not limited to, clear thermoplastics. The particular compounds are generally polymeric in nature including various chain lengths of polyoxyalkylenes thereon and are liquid in nature to facilitate handling and introduction within the target media. In addition, such ultraviolet absorbers also exhibit extremely low migratory properties thereby providing long-term protective benefits to the target media as well. This invention also concerns the end products, specific broadly defined types of compounds providing such beneficial characteristics, methods of making such low-color compounds, and methods of producing such clear, UV protected end products.

  本发明提供了一种新型的紫外线吸收化合物，其为液态，颜色低（因此可以在不必添加大量其他着色剂的情况下使用，以对抗这种变色），并且在以前尝试使用低色紫外线吸收剂的波长范围内提供高效的保护，这些化合物在各种介质中提供了出色、廉价和有益的紫外线防护，包括但不限于透明热塑性材料。这些特定的化合物通常具有聚氧烷基链的不同长度，并且具有液态性质，以便于在目标介质中进行处理和引入。此外，这些紫外线吸收剂还具有极低的迁移性能，从而为目标介质提供长期的保护效益。本发明还涉及最终产品、提供这种有益特性的特定广义化合物类型、制造这种低色化合物的方法以及生产这种透明的紫外线保护最终产品的方法。

  A base resistant, substantially amorphous fluoroelastomer comprising (1) 10-40 mole percent ethylene units, (2) 32-60 mole percent tetrafluoroethylene units, (3) 20-40 mole percent perfluoro(alkyl vinyl ether) units wheren the alkyl group contains 1-5 carbon atoms and (4) a cure-site monomer. Such fluoroelastomers are resistant to attack by amines, strong bases and hydrogen sulfide and possess a combination of good low temperature and high temperature properties and they are resistant to oil swell. To prevent fluoroelastomers of the type described above, with or without units of ethylene, that contain a bromine-containing olefin as a peroxide cure site from sticking to the mold cavity when cured an N,N,N',N'-tetrasubstituted 1,8-diaminonaphthalene is added to the fluoroelastomer having the formula: wherein R1, R2, R3 and R4 are independently alkyl groups of 1-6 carbon atoms, phenyl or benzyl, R, and R2 and/or R3 and R4 can be joined to form a 5- or 6-membered heterocyclic ring in which a carbon atom can be replaced by an oxygen or a sulfur atom, R, and R3 and/or R2 and R4 can be joined to form a heterocyclic ring of 6-20 carbon atoms in which a carbon atom can be replaced by an oxygen or a sulfur atom, X and Y are independently an alkyl group or an alkoxy group containing 1-4 carbon atoms and n is 0-3.

  一种耐碱、基本无定形的氟弹性体，由以下成分组成：(1) 10-40 摩尔百分数的乙烯单元；(2) 32-60 摩尔百分数的四氟乙烯单元；(3) 20-40 摩尔百分数的全氟（烷基乙烯基醚）单元，其中烷基含有 1-5 个碳原子；(4) 一种固化位单体。这种氟弹性体能抵抗胺、强碱和硫化氢的侵蚀，同时具有良好的低温和高温性能，并能抵抗油膨胀。为了防止上述类型的含或不含乙烯单元的含溴烯烃作为过氧化物固化位点的氟弹性体在固化时粘在模腔上，在具有以下式子的氟弹性体中加入了 N,N,N',N'-四取代的 1,8-二氨基萘： 其中 R1、R2、R3 和 R4 独立地为 1-6 个碳原子的烷基、苯基或苄基，R 和 R2 和/或 R3 和 R4 可以连接形成 5 或 6 元杂环，其中一个碳原子可以被氧原子或硫原子取代，R、和 R3 和/或 R2 和 R4 可连接形成 6-20 个碳原子的杂环，其中一个碳原子可被氧原子或硫原子取代，X 和 Y 独立地为含 1-4 个碳原子的烷基或烷氧基，n 为 0-3。
