Abstract

Embodiments of this invention relate to a composition comprising of (A) an anhydride and/or carboxylic acid functionalized, chlorinated olefin-based polymer and/or (b) a styrene-based polymer and/or a functionalized styrene-based polymer, (B) a polyamide wax slurry, and (C) organic solvent, and which composition can be used as an adhesive to bond a fabric to a polyolefin elastomer (POE) thermoplastic sheet, articles made from the composition, and methods of producing the composition and articles.

First claim

We claim:

1. A composition comprising at least the following:
A) a mixture of:
i) a maleic anhydride functionalized, chlorinated olefin-based polymer; and
ii) at least one of styrene-ethylene/butylene-styrene (SEBS) block copolymers, enhanced rubber segment styrene-ethylene/butylene-styrene block copolymers (ERS SEBS), or a maleic anhydride grafted styrene-ethylene/butylene-styrene copolymer (MAH-g-SEBS);

B) a polyamide wax slurry; and
C) an organic solvent.

2. The composition of claim 1 , comprising:
A) 0.5 to 40 wt % of the mixture;
B) 0.5 to 40 wt % of the polyamide wax slurry; and
C) 20 to 99 wt % of the organic solvent;
the wt % based on the total weight of the composition.

3. The composition of claim 1 , wherein the component C organic solvent is a non-aromatic and non-chlorinated solvent.

4. The composition of claim 1 wherein the maleic anhydride functionalized chlorinated olefin-based polymer of Component A has a maleic anhydride content from 0.75 to 3 wt %, based on the weight of the anhydride functionalized, chlorinated olefin-based polymer.

5. The composition of claim 1 wherein the chlorinated olefin-based polymer of Component A is a chlorinated propylene-based polymer.

6. An article comprising at least one component formed from the composition of claim 1 .

7. A composition comprising:
A) at least one polymer selected from the following:
i) an anhydride and/or carboxylic acid functionalized, chlorinated olefin-based polymer; or
ii) a styrene-based polymer and/or a functionalized styrene-based polymer; or
iii) a combination of i) and ii);

B) a polyamide wax slurry;
C) an organic solvent, and
D) a tackifier.

8. The composition of claim 7 , wherein component A is a maleic anhydride (MAH) functionalized chlorinated olefin-based polymer.

9. The composition of claim 7 , wherein component A is a mixture of
i) a maleic anhydride functionalized chlorinated olefin-based polymer, and
ii) a styrene-based polymer and/or a functionalized styrene-based polymer.

10. The composition of claim 9 wherein component A is a mixture of
i) a maleic anhydride functionalized chlorinated olefin-based polymer, and
ii) a styrene-ethylene/butylene-styrene (SEBS) block copolymer.

11. The composition of claim 9 wherein component A is a mixture of
i) a maleic anhydride functionalized chlorinated olefin-based polymer, and
ii) an enhanced rubber segment styrene-ethylene/butylene-styrene block copolymer.

12. The composition of claim 9 wherein component A is a mixture of
i) a maleic anhydride functionalized chlorinated olefin-based polymer, and
(ii) a maleic anhydride grafted styrene-ethylene/butylene-styrene copolymer.

13. The composition of claim 7 , wherein the component C organic solvent is a non-aromatic and non-chlorinated solvent.

14. An article comprising at least one component formed from the composition of claim 7 .

15. A coated substrate formed from the following:
a) a fabric substrate layer;
b) an adhesive layer which is formed from a first composition comprising at least the following:
A) at least one polymer selected from the following:
i) an anhydride and/or carboxylic acid functionalized, chlorinated olefin-based polymer; or
ii) a styrene-based polymer or a functionalized styrene-based polymer; or
iii) a combination of i) and ii);

B) a polyamide wax slurry; and
C) an organic solvent; and

c) an olefin-based layer formed from a second composition comprising at least one olefin-based polymer.

16. The coated substrate of claim 15 , wherein the adhesive layer further comprises a tackifier.

17. The composition of claim 15 , wherein the olefin-based layer (C) comprises a propylene/ethylene copolymer.

18. The composition of claim 15 , wherein the olefin-based layer (C) comprises a propylene/a-olefin copolymer, and further comprises at least one of:
(i) a homogeneously branched ethylene/a-olefin copolymer,
(ii) an olefin block copolymer (OBC), or
(iii) a random polypropylene copolymer.

19. The composition of claim 15 , wherein the olefin-based layer (C) comprises:
(i) a propylene/a-olefin copolymer; and
(ii) an olefin block copolymer (OBC).
