Dendrimeric Embedded Nano-Sized Cellulosic Beads Utilizing Molecular Architecture Scaffoldings for Dendrimer Assembly to Create Multi-Application Technologies therapeutic molecule itself. Subsequent NMR analysis of the hydrolyzed products from the benzylamine attached materials confirm the presence of the molecule substantiating the validity of our experimental methods to both attach and selectively release molecules from the surface of these materials.

Currently, cellulose is overlooked as a fiber due to it's incompatibility with the petroleum based polymers. Thus we explored many different compatilizers to increase the binding between cellulose and polypropylene. Experimental Plan: In this work we demonstrate the potential for use of a hydrophilic/hydrophobic block copolymer as coupling agents for cellulose/polypropylene composites. Current Results: Several films were made. The films tested were pure cellulose, cellulose with a few different 20% block copolymer of a polyether and Maleic Anhydride Polypropylene (MAPP). They were looked at under the microscope to make sure the polyether did not crystallize out of the film and that the amines appear to be evenly distributed in the film. The IR spectrum showed there to be some water Stress-Strain Curve of Polypropylene and cellulose A I M E 17
