Abstract
Abstract Decontaminating article comprising a preagglomerated, powdered polymer of bicyclo[2.2.1]-2-heptene or its methyl derivative in at least one fine-mesh textile bag. The bag is at least partially filled with the polymer. The decontaminating article can be used to absorb a liquid contaminating product, in particular petroleum hydrocarbon.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
30 words
A decontaminating article comprising: (a) a preagglomerated, powdered polymer of bicyclo[2.2.1]-2-heptene or its methyl derivative, and (b) at least one fine-mesh textile bag at least partially filled with the polymer.
Claim 2
Dependent Claim
30 words
A decontaminating article comprising: (a) a preagglomerated, powdered polymer of bicyclo[2.2.1]-2-heptene or its methyl derivative, and (b) at least one fine-mesh textile bag at least partially filled with the polymer.
Claim 3
Dependent Claim
15 words
The article according to claim 1, wherein the polymer is agglomerated with a plasticizing agent.
Claim 4
Dependent Claim
30 words
The article according to claim 2, wherein the plasticizing agent is selected from the group consisting of: liquid hydrocarbons; petroleum, paraffinic, aromatic and naphthenic oils; phthalates; adipates; sebacates; and alkylbenzenes.
Claim 5
Dependent Claim
24 words
The article according to claim 2, wherein the proportion of the plasticizing agent relative to the polymer is between 0.5 and 50% by weight.
Claim 6
Dependent Claim
26 words
The article according to claim 1, wherein the bag comprises at least one grasping means permitting the bag to be pulled or towed by mechanical means.
Claim 7
Dependent Claim
23 words
The article according to claim 1, wherein the polymer contained in the bag has a particle size of between 0.5 and 20 mm.
Claim 8
Dependent Claim
19 words
The article according to claim 1, further comprising at least one other absorbent agent mixed with the powdered polymer.
Claim 9
Dependent Claim
40 words
A process for absorbing a liquid contaminating product comprising the step of: arranging on the surface of the liquid at least one fine-mesh textile bag at least partially filled with a preagglomerated, powdered polymer of bicyclo[2.2.1]-2-heptene or its methyl derivative.
Claim 10
Dependent Claim
40 words
