Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
52 words
A process for the preparation of aluminoxanes which process comprises mixing a first solution of a trialkylaluminium compound in a liquid, dry, inert hydrocarbon solvent with a second solution of a liquid, inert, hydrocarbon solvent having water ultrasonically dispersed therein wherein the trialkylaluminium compound and the water react to produce an aluminoxane.
Claim 2
Dependent Claim
52 words
A process for the preparation of aluminoxanes which process comprises mixing a first solution of a trialkylaluminium compound in a liquid, dry, inert hydrocarbon solvent with a second solution of a liquid, inert, hydrocarbon solvent having water ultrasonically dispersed therein wherein the trialkylaluminium compound and the water react to produce an aluminoxane.
Claim 3
Dependent Claim
30 words
A process as claimed in claim 1 wherein the alkyl moiety of the trialkylaluminium compound is an alkyl group having in the range of from 1 to 5 carbon atoms.
Claim 4
Dependent Claim
17 words
A process as claimed in claim 2 wherein the alkyl moiety is a methyl or ethyl group.
Claim 5
Dependent Claim
30 words
A process as claimed in any one of the preceding claims wherein a molar ratio of trialkylaluminium compound to water in the range of from 0.65:1 to 2:1 is used.
Claim 6
Dependent Claim
20 words
A process as claimed in claim 4 wherein the molar ratio is in the range of from 0.75:1 to 1.25:1
Claim 7
Dependent Claim
14 words

Claim 9
Dependent Claim
25 words
A process as claimed in any one of the preceding claims wherein said first solution is added to said second solution while maintaining ultrasonic power.
