GRAFTED THERMOPLASTIC COMPOSITIONS AND FABRICATED ARTICLES THEREFROM

Document Type and Number:

WIPO Patent Application WO2001040374

Kind Code:

A3

Abstract:

This invention describes grafted blend compositions, processes for their preparation and fabricated articles, especially foams therefrom. The blends exhibit enhanced melt strength, melt elongation greater than or equal to about 20 mm/s, increased upper service temperature, increased modulus, and increased hardness. The grafted blend compositions have little or no high shear viscosity increase over a corresponding polymer of the same chemical composition absent the coupling agent.
