  • Color enhancement for resin blends
    Publication number: 20030146536
    Abstract: The use of a sulfonated polyester ionomer in a polyamide or polyester resin blend results in articles having enhanced dyeability, as demonstrated by an enhanced dye pick-up of at least 25% over resin blends without such sulfonated polyester ionomer.
    Type: Application

  • Phosphinimine modification of organic polymers and silicones
    Patent number: 6339166
    Abstract: Methods have been developed to produce phosphazene modified organic or siloxane polymers. The method includes (a) providing an organic or siloxane polymer comprising phosphine units, and (b) reacting the organic or siloxane polymer with a phosphazene azide compound under conditions wherein the phosphazene azide compound is bound to the phosphine unites in the polymer, thereby producing the phosphazene-modified organic or siloxane polymer. The organic polymer of step (a) is produced by reacting a first monomer comprising phosphine with a second monomer via free radical or anionic polymerization techniques to produce the organic polymer comprising phosphine units. The first and second monomers can be identical. A wide variety of organic polymer backbones can be modified using these techniques.
