| titleOfInvention | Manufacturing method of high branching degree acrylamide graft copolymer taking amylopectin as framework |
| abstract | The invention relates to a manufacturing method of high branching degree acrylamide graft copolymer taking amylopectin as the framework. The manufacturing method comprises the following steps: A) carrying out free radical grafting reaction with amylopectin, water-soluble vinyl monomers (such as acrylamide), optional carbamide and optional reaction type surfactant; and B) adding cross-linking monomer and cross-linking agent that can react with the cross-linking monomer to carry out modification reaction for obtaining wet slurry, then dry up the slurry optionally, so that high branching degree and slightly cross-linked water-soluble graft polymer (or copolymer) is prepared. At 25 DEG C, the rotary viscosity the aqueous solution of which the concentration is 2wt% is generally within the range of 2000 to 70,000 mPa.s, wherein the aqueous solution is made of water. The graft polymer is used as biomedical material, water absorbing material, water-based ink coating, polymer additives, separation film material or photosensitive material. |
