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 a current temperature and an activation temperature; (b) causing the current temperature to sufficiently exceed the activation temperature to thermally initiate a substantially adiabatic polymerization and provide a free-flowing copolymer; wherein the α,β-unsaturated carboxylic acid derivative is selected from the group consisting of an acid, an ester, an amide, an amidine, and a salt, and wherein said causing the current temperature to sufficiently exceed the activation temperature involves causing said combination to be heated to at least about 180° F.
