  • reaction need not be complete in order to obtain the advantages of my invention. That is, not all of the reactive anhydride or carboxylic halide groups in the polymerized compounds need undergo reaction. However, it is generally advantageous to have at least 10 percent of such reactive groups combined with the ultraviolet absorbing component.

  • the condensations can advantageously be carried out in the presence of an acid condensing agent, such as glacial acetic acid, etc. While the reaction mixture can be heated, there is generally no advantage in doing so due to the exothermic nature of the reaction.
