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.

The Xanthate Method of Grafting: XI. Grafting of Methylmethacrylate on Hardwood Pulp pure cellulose,solely. It can also be applied for the grafting of chemical as well as mechanical softwood pulps.. The abovementioned method has recently been applied to the grafting of acrylonitrile to aspen., or acrylonitrile and/or styrene to birch..

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.
