ABSTRACT:
This invention relates to a process for making laminar articles by blending multicomponent pellets of a heterogeneous blend of a barrier resin, typically a condensation polymer, and a compatibilizer with a polyolefin. The pellets advantageously prevent segregation of the barrier resin and the compatibilizer during processing. This provides uniform, reproducible laminar articles with improved barrier properties and mechanical properties. The articles exhibit good fluid barrier and mechanical properties.
