Abstract
Abstract Quaternary Ammonium Co-Polymers formed by the condensation of at least two di-functional tertiary amines and a molar quantity of 1,4-dihalo-2-butene that is equal to the molar sum of the di-functional tertiary amines in the mixture are used to control the proliferation of bacteria.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
89 words
A method of controlling the proliferation of bacteria which comprises applying to said bacteria an effective amount sufficient to inhibit their growth, of a product formed by the condensation of a mixture of difunctional tertiary amines and a molar quantity of 1,4-dichloro-2-butene that is substantially equal to the molar sum of the mixture of the difunctional tertiary amines, said mixture of difunctional tertiary amines being selected from the group consisting of (a) 1,4-bis-(morpholino)-2-butene and N,N'-di-lower alkyl piperazine, (b) 1,4-bis-(dimethylamino)-2-butene and 1,4-bis-(N-morpholino)-2-butene, and (c) 1,4-bis-(dimethylamino)-2-butene, N,N'-di-lower alkyl piperazine and 1,4-bis-(N-morpholino)-2-butene.
Claim 2
Independent Claim
89 words
A method of controlling the proliferation of bacteria which comprises applying to said bacteria an effective amount sufficient to inhibit their growth, of a product formed by the condensation of a mixture of difunctional tertiary amines and a molar quantity of 1,4-dichloro-2-butene that is substantially equal to the molar sum of the mixture of the difunctional tertiary amines, said mixture of difunctional tertiary amines being selected from the group consisting of (a) 1,4-bis-(morpholino)-2-butene and N,N'-di-lower alkyl piperazine, (b) 1,4-bis-(dimethylamino)-2-butene and 1,4-bis-(N-morpholino)-2-butene, and (c) 1,4-bis-(dimethylamino)-2-butene, N,N'-di-lower alkyl piperazine and 1,4-bis-(N-morpholino)-2-butene.
Claim 3
Dependent Claim
12 words
The method of claim 1 wherein N,N'-di-lower alkyl piperazine is N,N'-dimethyl piperazine.
