Abstract: Polymeric blends having improved flame retardance properties and good ductility at low temperatures are disclosed. The blend is formed from (A) a photoactive additive containing a photoactive group derived from a monofunctional benzophenone; and (B) a polymer resin which is different from the photoactive additive. The additive can be a compound, oligomer, or polymer. When exposed to ultraviolet light, crosslinking will occur between the photoactive additive and the polymer resin, enhancing the chemical resistance and flame retardance while maintaining ductility.

Abstract: Disclosed herein are polycarbonate fibers and fibrous substrates, such as papers, containing such fibers. The polycarbonate fibers are produced from a polymeric composition comprising a cross-linkable polycarbonate containing endgroups derived from a monofunctional benzophenone or containing repeating units derived from a difunctional benzophenone. The polycarbonate fibers can be combined with other fibers to form the fibrous substrate. Upon exposure to ultraviolet light, crosslinking of the polycarbonate fibers will occur, improving various properties of the fibrous substrate.

Abstract: Melt polymerization processes for producing photoactive additives are disclosed. The photoactive additives are cross-linkable polycarbonate resins formed from a benzophenone, a dihydroxy chain extender, a carbonate precursor, and a catalyst. The additives can be produced without the use of phosgene or dichloromethane, and can be cross-linked with other polymers upon exposure to UV radiation.

Abstract: Methods of making articles using additive manufacturing processes are disclosed. The article is built up from a multitude of layers. At least one layer includes a modeling material comprising a cross-linkable polycarbonate resin containing a photoactive group derived from a benzophenone. When exposed to an effective dosage of ultraviolet radiation, the modeling material crosslinks. This improves various properties of the final article.
