A series of hydrogels based on glyceryl methacrylate (pGMA) were prepared with different ratios of ethylene glycol dimethacrylate (EGDMA) and ethyl methacrylate (EMA) in order to vary the degree of crosslinking and the degree of hydrophobicity of the matrices, respectively. The swelling be...
The synthesis of two novel hydrogel adhesive films, poly(butoxy- Entprol) and poly(butoxy/ethylene-Entprol) was accomplished by crosslinking either epoxy end-capped oligomeric-butoxy-Entprol or epoxy end-capped oligo meric-butoxy/ethylene-Entprol with 5-10 mole% diethylenetriamine. The two...
Characteristic properties of oligosaccharide-substituted poly styrenes as a hepatocyte-specific culture substratum were investigated from the viewpoint of adsorption and recognition. X-ray photoelectron spectra sug gest that the adsorption of the polymer onto a polystyrene film occurred in near...
The biodegradation of dextran, reduced dextran dialdehyde and dextran monosuccinate ester was investigated using isolated rat liver lysosomes. It was demonstrated that chemical modification of the parent dex tran resulted in a reduced degradability. The action of the exo-enzyme α-glucos idase...
Polyanion-cis-diammineplatinum(II) complexes were synthesized by the reaction of cis-[Pt(NH3)2(OH2)2](NO 3)2 with the polyanions containing vic- dicarboxylate ions along the polymer chain. The eleven polyanions used for this synthesis were the hydrolysis products of polymers obtained by radical...
Chitosan, a polycationic polymer and waste product from the sea food processing industry, is an abundant natural resource that has, as yet, not been fully utilized. Advantages of this polymer include availability, low cost, high biocompatibility, biodegradability and ease of chemical...
