Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
104 words
A process for producing a high molecular weight organoaluminum polymer by reacting an organoaluminum compound with water, the improvement comprising using as reactants an organoaluminum compound represented by the general formula (I): (wherein X and Y may be the same or different and are each a hydrogen atom, an alkyl group, an alkoxyl group, or an acyloxyl group, and R 1 is at least one organic radical) and an organic acid in an amount such that the total amount of the organic acid and the acyloxyl group contained in the organoaluminum compound is from 1.2 to 11 moles per mole of the organoaluminum compound.
Claim 2
Dependent Claim
104 words
A process for producing a high molecular weight organoaluminum polymer by reacting an organoaluminum compound with water, the improvement comprising using as reactants an organoaluminum compound represented by the general formula (I): (wherein X and Y may be the same or different and are each a hydrogen atom, an alkyl group, an alkoxyl group, or an acyloxyl group, and R 1 is at least one organic radical) and an organic acid in an amount such that the total amount of the organic acid and the acyloxyl group contained in the organoaluminum compound is from 1.2 to 11 moles per mole of the organoaluminum compound.
Claim 3
Dependent Claim
23 words
The process as claimed in Claim 1, wherein the molar ratio of the water to the organoaluminum compound is from 1:1 to 3.5:1.
Claim 4
Dependent Claim
24 words
The process as claimed in Claim 1 or 2, wherein the organic acid is added during the reaction of the organoaluminum compound and water.
Claim 5
Dependent Claim
25 words
The process as claimed in Claim 1 or 2, wherein the organic acid is added prior to the reaction of the organoaluminum compound and water.
Claim 6
Dependent Claim
26 words
5 . The process as claimed in Claim 1 or 2, wherein the organic acid is added after the reaction of the organoaluminum compound and water.
Claim 7
Dependent Claim
37 words
The process as claimed in Claim 1 or 2, wherein a part of the organic acid is added during the reaction of the organoaluminum compound and water, and the remainder is added after completion of the reaction.
Claim 8
Dependent Claim
40 words
The process as claimed in Claim 1 or 2, wherein the organoaluminum compound is a compound represented by the general formula (II): (wherein X and R 1 are as defined above, and R 2 is at least one organic radical).
Claim 9
Dependent Claim
41 words
The process as claimed in Claim 1 or 2, wherein the organoaluminum compound is a compound represented by the general formula (III): (wherein R 1 and R 2 are as defined above, and R 3 is at least one organic radical).
