## Abstract

A mixture curable in the presence of a metallic catalyst to provide a material for thermally insulating a substrate useable subsea. The mixture comprises from 55 to 99% by weight of a norbornene monomer and a water insoluble polymer filler. The water insoluble polymer filler comprises polystyrene or polypropylene, or derivatives thereof.

### Claim 2 (depends on 1)

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

### Claim 3 (depends on 1)

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

### Claim 4 (depends on 1)

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

### Claim 5 (depends on 1)

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

### Claim 6 (depends on 1)

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

### Claim 7 (depends on 1)

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.

### Claim 8 (depends on 1)

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

### Claim 9 (depends on 1)

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

### Claim 10 (depends on 1)

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

### Claim 11 (depends on 1)

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

### Claim 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.

### Claim 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.
