PLASTIC SURFACES HAVING IMPROVED SURFACE CHARACTERISTICS

摘要

The disclosure provides a melt processible theromoplastic composition, comprising a major proportion of a base polymer comprising a first melt processible thermoplastic polymer having a first Fedor's solubility parameter and a first viscosity; and a combination of a carrier polymer and a surface modifying additive, the carrier polymer comprising a second melt processible thermoplastic polymer which has a second solubility parameter that is at least about 2.5 (J/cm^3)^1/2 lower than the first solubility parameter, and a second viscosity, the carrier polymer being adhered to the surface modifying additive, and wherein the first viscosity is at least about 25 times the second viscosity.
