Abstract

This invention relates to N,N-diallyl-3-hydroxy azetidinium salts, homo- and co-polymers thereof; and the preparation thereof. This invention also relates to the use of the above polymers as demulsifiers.

Claims

1. Homo- and copolymers of N,N-diallyl-3-hydroxy azetidinium halide, formed under free radical conditions where, in the copolymers, one of the monomers of the copolymer is a vinyl monomer.

3. The copolymer of claim 1 where the monomer is acrylamide.

2. Homo- and copolymers of N,N-diallyl-3-hydroxy azetidinium chloride, formed under free radical conditions where, in the copolymers, one of the monomers of the copolymer is a vinyl monomer.

4. The copolymer of claim 2 where the monomer is acrylamide.
