Abstract:
1. A method for forming a graft copolymer comprising: (a) combining water, a carbohydrate, at least one α,β-unsaturated carboxylic acid derivative, and a catalyst to form a combination having thermally initiated polymerization conditions; (b) introducing the combination to a reactor having a reaction zone providing thermally initiated polymerization conditions; and (c) thermally initiating polymerization to form the graft copolymer therein under substantially adiabatic conditions; wherein the α,β-unsaturated carboxylic acid derivative is selected from the group consisting of an acid, an ester, an amide, and a salt, and the catalyst is capable of initiating polymerization when subjected to initiation conditions.
