    摘要: In one aspect of the present invention, a UV-protective coating composition is described. The UV protective coating composition includes an acrylate polymer; and a non-crystallizing UV-absorber composition. The non-crystallizing UV absorber composition includes a dibenzoylresorcinol and at least one triazine compound. The dibenzoylresorcinol is present at a level in the range of from about 10 weight percent to about 25 weight percent, based on the total weight of the coating composition. Also provided is an article that includes the UV protective coating composition, and a method to protect the article.

    摘要: Weatherable polycarbonate compositions (formulations or blends) comprise at least one of a piperazinone and piperazine dione based HALS, and polyether based. The combination of these HALS and polyether based polymers exhibits a synergy that results in enhanced protection of the polycarbonate compositions by imparting photostability to the polycarbonate formulations, thereby reducing yellowing or other forms of light induced degradation.

    摘要: An improved method of making methylene-bridged 4,6-dibenzoylresorcinol dimers in a single step in high yield quantities is provided. The method heats a 4,6-dibenzoylresorcinol (DBR) with a para-aldehyde or an aromatic aldehyde in a carboxylic acid solvent in the presence of a strong acid catalyst.
