ABSTRACT:
A coextrusion employing a tie layer between two layers of different polymer materials. The tie layer is formed in the extrusion melt of a composition comprising one of the two polymer materials and a coupling agent that includes functional groups that are reactive at least with functional groups on the second polymer. The coupling agent may be incorporated into the tie layer material in amounts above 5% by weight.
