Tie-layer formulation and method of manufacture of laminate therewith

摘要

A multi layer thermoplastic polymer alloy (220, 320) is provided. The multi layer alloy includes a skin of thermoplastic polymer alloy (20, 120) having non-polar segments and a tie-layer having non-polar segments and polar functional groups. The non-polar segments of the tie-layer are bondable with the non-polar segments of the thermoplastic polymer alloy skin. Similarly, the polar functional groups of the tie-layer are bondable or reactable with a surface layer (230, 232, 332).
