Popis: | The Hofmann modification of polyacrylamide to yield vinylamine homo- or copolymers was reinvestigated in order to determine the real scope of a procedure of great potential interest in polymer chemistry. The conditions of the treatment by sodium hypochlorite followed by concentrated sodium hydroxide at low temperature (0 o C) were adjusted to avoid or to limit side-reactions between pendant reactive groups. A broad range of initial mole ratio a of sodium hypochlorite per initial amide function (0,05 |
