METHOD FOR THE PRODUCTION OF GRAFTED COPOLYMERS MADE OF STARCH, TERT-ALKYLAZOCYANOCARBOXYLIC ACID ESTERS AND GRAFTED COPOLYMERS AND THE USE THEREOF

摘要

The present invention relates to formed for producing graft copolymer and skeleton from starch or its derivative. The preparation is to carry out coupling by tertiary alkyl azo cyanocarboxylic acid esters starch to pass through radical reaction and vinyl monomer. The present invention also relates to the applications of the graft copolymer of starch, its dispersion and the graft copolymer.
