Method of Preparing a Zwitterionic Copolymer |
| abstract |
A method for preparing a zwitterionic co-polymer comprising the steps of: a) providing a solution of at least one ethylenically unsaturated polymerizable zwitterionic monomer dissolved in a solvent; b) combining said solution of zwitterionic monomer with at least one co-monomer being selected from cationic, anionic and non-ionic ethylenically unsaturated monomers; c) polymerizing the zwitterionic monomer and said at least one co-monomerin the presence of said solvent to form a solution or dispersion of co-polymer; and, d) replacing at least part of said solvent with a further solvent in which said co-polymer shows sufficient solubility to form a solution of said co-polymer in that further solvent. Step b) and step c) of this method may be performed sequentially or concurrently. |
