Structure-Controlled Synthesis of Regiospecifically Modified Polysaccharides Starting from a Pyrolys prepared. Ring-opening polymerization using these anhydro sugar derivatives as monomers, followed by debenzylation, afforded structurally well-defined (1→6)-α-.-glucopyranan (linear dextran) derivatives: (a) 3-.-Methyl-(1→6)-α-.-glucopyranan, (b) 3-.-octadecyl-(1→6)-α-.-glucopyranan, (c) 3-.-methyl

Transport Properties of Membranes Containing Chitosan Derivativesosan (MGC)-GC-PVSK systems, were prepared in aqueous solution at various hydrogen ion concentrations. The molecular composition of each PEC was dependent on pH, since the degree of dissociation and conformation of GC were affected by pH. PEC membranes were prepared, and their transport properties we

Sorption Behavior of Chemically Modified Chitosan Gelsy. The state of water in N-acylated chitosan gels was studied by DSC technique. The amounts of two states of water, freezable and nonfreezable water, were found to depend on the chemical and physical structure of the gels. The interaction between chitosan and its acyl (octanoyl, dodecanoyl, octadeca

This paper will summarize some pertinent information for certain biotechnology derived polymers, such as wool, cotton, silk, rubber casein and the cellulosics. In addition, some potential new polymers, and polymer applications, from biotechnology are briefly discussed.

IR, MS and other physical data are consistent with the presence of organotin-modified lignin formed through condensation with the lignin-hydroxyl groups.
