Abstract
The present invention concerns a controlled structure copolymer comprising at least two different parts, a first part A, amphoteric or zwitterionic, including anionic or potentially anionic units, and cationic or potentially cationic units, or zwitterionic units, and another part B, non amphoteric or zwitterionic. Said copolymer further exhibits a high potential for adaptation, through variation in its composition, in order to improve or modify the properties of compositions in which it is introduced.

A controlled structure copolymer comprising at least two parts A and B of different compositions, part A comprising ionic or potentially ionic units, wherein:
- part A is an amphoteric or zwitterionic part, comprising:
- cationic or potentially cationic units AC,
- anionic or potentially anionic units AA, and
- optionally, hydrophilic and/or hydrophobic neutral units AN,
- and/or
- zwitterionic units AZ,
- optionally, cationic or potentially cationic units AC,
- optionally, anionic or potentially anionic units AA, and
- optionally, hydrophilic and/or hydrophobic neutral units AN,
- part B is not an amphoteric or zwitterionic part.
