  • Publication number: 20140179821
    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.

  • Publication number: 20140018463
    Abstract: A surface-modified polymer is described, comprising a polymeric material and a self-assembling monolayer covalently bound thereto. The monolayer comprises monoethylene glycolated-OH (MEG-OH); 2-(3-trichlorosilyl-propyloxy)-ethyl-trifluoroacetate (7-OEG or MEG-TFA); 2,2,2-trifluoroethyl-13-trichlorosilyl-tridecanoate (TTTA); OEGylated TTTA (OEG-TTTA); S-(2-(2-(2-(3-trichlorosilyl-propyloxy)-ethoxy)-ethoxy)-ethyl)-benzenethiosulfonate (OEG-TUBTS); or a combination thereof. Methods are described for forming a surface-modified polymer by surface activation, such as with plasma. By utilizing the surface-modified polymer to make medical equipment or devices for contacting biological fluids, a reduction in surface fouling and thrombus formation can result. Advantageously, polymeric equipment or components so modified may have a reduction in unwanted chemical interactions leading to fouling or clotting.
