Biodegradation of Blends Containing Poly (3-Hydroxybutyrate-CO-Valerate)(PCL), poly (styrene-co-35%-acrylonitrile), (SAN), or poly (styrene), (PS), as the second component. Blend concentrations of 20/80, 50/50 and 80/20 weight percents were solvent cast from chloroform and analyzed for miscibility using DSC. Biodegradation studies were conducted using an exposure to the

The Biosynthesis of Unusual Polyamides Containing Glutamic Acidcid (γ-PGA) has been carried out. The introduction of additional nutrients after a 3 day culture period improved polymer production (in γ-PGA g/L) and gave polymer of higher molecular weight relative to control samples. Modification of the product polyamides by synthesis of the corresponding ethyl a

Vernonia Oil: A New Reactive Monomering three epoxy rings and three carbon-carbon double bonds. It has several advantages over other epoxidized vegetable oils produced industrially and appears to be a very attractive raw material for three large volume industrial applications. First, vernonia oil is characterized by very low viscosity

Interpenetrating Polymer Networks Based on Functional Triglyceride Oils and Other Not Yet Commercialm seed oils to a spider’s silk. While the wide use of these materials may not be economically viable at present, as oil prices continue to rise, these materials will become more attractive commercially. In this paper, the use of triglyceride oils to form novel interpenetrating networks is reviewed,

Structural Characterization of Organostannane — Kraft Ligninccessfully incorporated into Kraft lignin (Indulin AT and C) through the classical interfacial condensation of organotin chlorides with lignin. IR, MS and other physical data are consistent with the presence of organotin-modified lignin formed through condensation with the lignin-hydroxyl groups.

Bacterial Polysaccharides for Use in Food and Agriculturene application involves mass production, purification and sale of such polymers as additives. Recent research on potential new additives will be illustrated by discussions of the gelation mechanism of gellan gum, a broad spectrum gelling agent, and early studies on the production, purification and a
