Abstract: Nanocrystalline cellulose (NCC)-based supramolecular materials, a method for their preparation and their use in thermoplastic and thermoset polymer composites are disclosed. Supramolecular materials of NCC and one or two polymers are synthesized by in situ surface graft copohmerization in a multitude of solvent systems, including water. The nano-scale size supramolecular materials are engineered to have a unique combination of lower polarity and high hydrophobicity and function as copohmers for demanding pohmeric systems such as, but not limited to, polyolefins and polyesters. Nanocomposite materials of enhanced functionality and mechanical properties are produced by compounding the NCC-based supramolecular materials with polymer matrices. The supramolecular materials are used in composite development for packaging materials, structural composites for automotive and construction, as sandwiched foam composites or, combined with biocompatible polymers, in medical applications.

Abstract: Biodegradable graft copolymers derived from a carbohydrate, including nitrogen-containing carbohydrates and modified carbohydrates, and at least one α,β-unsaturated carboxylic acid derivative having superabsorbent properties are disclosed in addition to the substantially adiabatic polymerization process by which the graft copolymers are made. The methods disclosed can be carried out in a variety of currently available stirred and/or continuous commercial reactors. Polymerizations carried out with starch have surprisingly produced substantially quantitative yields of graft copolymer free of residual monomer produced as a moist copolymer. Product work-up typically involves an optional neutralization and drying.
