Abstract

Claims (21)

1. A thermal insulating material mixture curable in the presence of a metallic catalyst for thermally insulating a subsea substrate, wherein the mixture consists essentially of:

5-octyl-2-norbornene;

tricyclopentadiene; and

a water insoluble polymer filler, wherein the water insoluble polymer filler comprises polystyrene or polypropylene, or derivatives thereof.

2. A mixture according to claim 1 , wherein the metallic catalyst is a ruthenium-based catalyst, wherein the ruthenium-based catalyst is a Grubbs catalyst.

3. A mixture according to claim 1 , wherein the water insoluble polymer filler is micronized.

4. A mixture according to claim 1 , wherein the water insoluble polymer filler is a particulate filler.

5. A mixture according to claim 1 , wherein the water insoluble polymer filler comprises micronized polystyrene.

6. A mixture according to claim 1 , wherein the water insoluble polymer filler comprises micronized polypropylene.

7. A mixture according to claim 1 , wherein a combination of the 5-octyl-2-norbornene and the tricyclopentadiene is from 60 to 99% by weight of the mixture.

8. A mixture according to claim 1 , wherein the mixture comprises from 1 to 50% by weight of the water insoluble polymer filler.

9. A mixture according to claim 1 , wherein the mixture comprises from 15 to 45% by weight of the water insoluble polymer filler.

10. A mixture according to claim 1 , wherein the mixture comprises from 20 to 40% by weight of the water insoluble polymer filler.

11. A mixture according to claim 1 , wherein the mixture comprises from 25 to 30% by weight of the water insoluble polymer filler.

12. A material for thermally insulating a substrate useable subsea, wherein the material is the cured reaction product of a mixture consisting essentially of:

5-octyl-2-norbornene;

tricyclopentadiene; and

a water insoluble polymer filler, wherein the water insoluble polymer filler comprises polystyrene or polypropylene, or derivatives thereof.

13. A method, wherein the method comprises:

forming a mixture consisting essentially of: 5-octyl-2-norbornene, tricyclopentadiene and a water insoluble polymer filler by mixing the 5-octyl-2-norbornene, tricyclopentadiene, and water insoluble polymer filler, wherein the water insoluble polymer filler comprises polystyrene or polypropylene, or derivatives thereof;

allowing the mixture to cure in the presence of a metallic catalyst to provide a material for thermally insulating a substrate useable subsea.
