The invention relates to a method for the production of grafted copolymers with a skeleton formed from starch or the derivatives thereof. Production occurs by means of tert-alkylazocyanocarboxylic acid esters of starch which are coupled by radical reaction with vinyl monomers. The invention also relates to grafted copolymers of starch, the dispersions thereof and the use of said grafted copolymers.
L'invention concerne un procédé pour produire des copolymères greffés présentant un squelette formé d'amidon et/ou de dérivés d'amidon. La production a lieu par l'intermédiaire d'esters d'acide tert-alkylazocyanocarboxylique d'amidon qui sont couplés à des monomères vinyliques par réaction radicalaire. L'invention concerne également des copolymères greffés d'amidon, leurs dispersions, ainsi que l'utilisation de ces copolymères greffés.
