  • Solid concentrate composition for polymeric chain extension
    Publication number: 20080206503
    Abstract: A solid concentrate composition for use in promoting chain extension within a polymer, and corresponding method, includes a chain extender and a non-reactive carrier resin or a co-reactive carrier resin. The concentrate composition prevents the premature reaction of the chain extender within a molding apparatus, increasing the dispersion of the chain extender throughout the polymer, and thereby preventing gelation and promoting homogeneous chain extension.
    Type: Application
