Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
122 words
The process for preparing polyvinyl quaternary amines which comprises reacting an aqueous solution of a tertiary amine with ethylene dihalide in the mol ratio of about 2 to 1 at a temperature of at least about 100° C. for a time sufficient to produce a vinyl quaternary amine, the tertiary amine being of a structure such that under the conditions of the reaction it is capable of both adding to one end of the ethylene dihalide and causing dehydrohalogenation to yield a vinyl quaternary amine, and continuing the reaction so that the vinyl quaternary amine is further polymerized to form the polyvinyl quaternary, the amine being a dimethyl aliphatic hydrocarbon amine where the aliphatic hydrocarbon group has 6 to 30 carbon atoms.
Claim 2
Dependent Claim
122 words
The process for preparing polyvinyl quaternary amines which comprises reacting an aqueous solution of a tertiary amine with ethylene dihalide in the mol ratio of about 2 to 1 at a temperature of at least about 100° C. for a time sufficient to produce a vinyl quaternary amine, the tertiary amine being of a structure such that under the conditions of the reaction it is capable of both adding to one end of the ethylene dihalide and causing dehydrohalogenation to yield a vinyl quaternary amine, and continuing the reaction so that the vinyl quaternary amine is further polymerized to form the polyvinyl quaternary, the amine being a dimethyl aliphatic hydrocarbon amine where the aliphatic hydrocarbon group has 6 to 30 carbon atoms.
Claim 3
Dependent Claim
24 words
The process of claim 1 where the tertiary amine is where R is alkyl of 8-20 carbon atoms and the temperature is 100° to
Claim 4
Dependent Claim
51 words
The process of claim 2 where the tertiary amine is ##STR7## where R is an alkyl group having about 12 to 18 carbon atoms, the reaction temperature is 120° to 180° C., and the solvent component of the aqueous solution is water or water in combination with a water miscible alcohol.
Claim 5
Dependent Claim
12 words
The process of claim 1 where the ethylene dihalide is ethylene dichloride.
Claim 6
Dependent Claim
12 words
The process of claim 2 where the ethylene dihalide is ethylene dichloride.
Claim 7
Dependent Claim
12 words
The process of claim 3 where the ethylene dihalide is ethylene dichloride.
