Tie-layer materials, articles and methods for making and using same
A composite article is provided that includes a polyolefin layer, a tie-layer, and a non-polyolefin. The tie-layer may comprise a silicon modified polyolefin. Methods are also provided for adhering a polyolefin to a non-polyolefin. Such articles may used, for example, in composite tubing.

R is selected independently for each occurrence from the group consisting of H, alkyl, alkenyl, alkynl, halogen, aralkyl, aryl, polycyclyl, and carbocycles;
X 1 independently for each occurrence represents a moiety that is capable of bonding to said non-polyolefin by a chemical reaction; and
z represents the number of linkages between the Si(R) 3−z moieties, and is an integer from 1 to 3.
2. The composite article of claim 1 , wherein for each occurrence, R 1 and R 2 and are selected independently from the group of consisting of alkyl, alkenyl, and alkynyl, —O—, alkoxy, aryl, polycyclyl, carbocycles, and a bond.
