Abstract

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.

Claims (30)

1. A composite article comprising a polyolefin layer, a tie-layer, and a non-polyolefin, wherein said tie-layer comprises:

wherein represents a polyolefin segment;

R 1 independently for each occurrence represents bivalent organic moiety or a bond;

R 2 independently for each occurrence represents bivalent organic moiety, or a bond;

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.

3. The composite article of claim 2 , wherein z is 1.

4. The composite article of claim 2 , wherein z is 2.

5. The composite article of claim 2 , wherein z is 3.

6. The composite article of claim 1 , wherein R 2 for each occurrence independently represents an acetyl moiety, alkyl ether, arylether, —O—, or a bond.

7. The composite article of claim 1 , wherein X 1 comprises a vinyl, epoxy or amine moiety.

8. A composite tube, comprising the composite article of claim 1 .

9. A composite article comprising a polyolefin layer, a tie-layer, and a non-polyolefin, wherein said tie-layer comprises:

wherein represents a polyolefin segment;

R 1 independently for each occurrence represents bivalent organic moiety or a bond;

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

p is an integer from 0 to about 1000.

10. The composite article of claim 9 , wherein R is —O-alkyl or —O—H.

11. The composite article of claim 9 , wherein R 1 is selected independently, for each occurrence, from the group consisting of alkyl, alkenyl, and alkyny, —O—, alkoxy, aryl, heterocyclyl, polycyclyl, carbocycles, and a bond.

12. The composite article of claim 9 , wherein X 1 comprises a vinyl, epoxy or amine moiety.

13. A composite article comprising a polyolefin layer, a tie-layer, and a non-polyolefin, wherein said tie-layer comprises

wherein represents a polyolefin segment;

R 1 independently for each occurrence represents bivalent organic moiety or a bond;

R is selected independently for each occurrence from the group consisting of H, alkyl, alkenyl, alkynl, halogen, aralkyl, aryl, heterocyclyl, polycyclyl, and carbocycles; and

X 1 independently for each occurrence represents a moiety that is capable of bonding to said non-polyolefin moiety by a chemical reaction.

14. The composite article of claim 13 , wherein for each occurrence, R 1 is selected independently from the group consisting of alkyl, alkenyl, and alkynyl, —O—, alkoxy, aryl, heterocyclyl, polycyclyl, carbocycles, and a bond.

15. The composite article of claim 13 , wherein X 1 comprises a vinyl, epoxy or amine moiety.
