Abstract: The present invention concerns new cationic quaternary ammonium compounds which exhibit excellent adsorption properties on negatively charged surfaces. These ones can notably be obtained firstly by reacting an internal ketone with a twin-tail amine under reductive amination conditions to obtain a twin tail triamine, then subjecting the twin tail triamine to a quaternization reaction. They can also obtained be obtained by the quaternization reaction of a certain diamine.

Abstract: The instant invention concerns a process for fragmenting a polymer chain, comprising an oxidative degradation step wherein the polymer chain is contacted with a reduced form of a metal M and an oxidant such as dioxygen, and wherein the polymer carries covalently bound chemical groups acting as a ligand of said reduced form of the metal M.
The invention also relates to methods making use of this fragmentation process as a first step of a degradation process of the polymer especially useful for avoiding the negative impact of a polymer to the environment. In this connection, the invention relates to the use of polymers carrying chemical groups acting as a ligand for a reduced form of a metal M, as a polymer biodegradable in an environment wherein the reduced form of a metal M is present.
