| titleOfInvention | PROCEDURE FOR THE PREPARATION OF POLYQUATERNARY POLYMERS. |
| abstract | Process for the preparation of polyquaternary polymers starting from polymeric polyamines containing at the same time several beta hydrogens and several nitrogen groups and containing at least one reactive hydrogen, characterized in that it comprises the steps of first reacting said polyamine with sufficient organic agent with reactive nitrogen at a temperature between the environment and about 90ยบ C, until the nitrogen groups of said polyamine are completely covalently coupled with organic radicals derived from said organic agent with reactive nitrogen, maintaining the pH at 7.5-12 and completing said reaction by quaternization of said polyamine reacted with a quaternizing agent at a pH of 7.5-9 within the aforementioned temperature limit, said quaternization reaction being free of degradation of the length of the polymeric polyamine chain.
