Sugar Containing Polymers Derived from Organostannes and Bis-(Cyclopentadienyl) Titanium Dichloridentaining moiety is indicated by color (in the case of Ti), elemental and thermal analyses, mass spectroscopy and infrared spectroscopy. The crosslinked nature of the product is indicated by solubility studies. The formation of the M-O-R linkage is consistent with previous studies.

Chemically Modified Carbohydrates as Highly Efficient Regio- and Stereoselective Catalysts for Hydroy of these macromolecules in comparison to synthetic polymers. We introduced different polysaccharides as polymeric supports for catalysts in order to obtain polymer catalysts which are applicable in homogeneous phase.

Graft Copolymerization onto Cellulose Acetate and Wood Using Anionic Polymerizationials with specific and improved properties for a wide range of applications. The properties of this molecular composite would be substantially better than the properties of either homopolymer alone. If the individual polymer segments in copolymers have opposite properties such as polar and nonpolar
