A method for the preparation of graft copolymers of starch, tertiary - alkylazocyanocarbonsäureester as well as graft copolymers and their use

摘要

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.
