Disclosed is a method for inhibiting corrosion on corrosion-sensitive metal with a bacterial exopolysaccharide. Specifically, exopolysaccharides precipitated from NRRL bacterial strains B-1254, B-1355, B-1498, and B-1500 coated on low carbon steel alloy confers anti-corrosion coating to corrosion sensitive metals. Preferably with the coating, the corrosion rate for coated metal is less than 0.4 milli-inch per year.

Anti-corrosion coating utilizing bacterial precipitated exopolysaccharides

Described are polymers and copolymers containing sorbitol, citric acid, starch, aspartic acid, succinic anhydride, adipic acid mixtures thereof, methods of their synthesis and their uses.

Methods of synthesis of polymers and copolymers from natural products

A polymer composition includes a first component being a hydroxy-functional polymer, a second component being a natural polymer and a third component being a thermoplastic polyester. The first component, second component and third component are compounded to form a polymer composition.

Biodegradable polymer compositions methods for making same and articles therefrom

Disclosed are methods of synthesis of polysuccinimide and a copoly(succinimide-aspartate) using a supercritical fluid.

Synthesis of polysuccinimide and copoly(succinimide-aspartate) in a supercritical fluid

A method of making a biodegradable polymer composition including the steps of providing a first component being either one of a thermoplastic poly(hydroxy ester ether) or a synthetic, hydroxy-functional polymer and providing a second component being a natural polymer. The method includes the steps of mixing the first component and second component together to form a mixture, compounding the mixture, and pelletizing the compounded mixture to form pellets of a biodegradable polymer composition.

Method of making biodegradable polymer compositions

Biodegradable polymer compositions, methods for making same and articles therefrom

A polymer composition uncludes a first component being a hydroxy-functional polymer, a second component being a natural polymer and a third component being a thermoplastic polyester. The first component, second component and third component are compounded to form a polymer composition.

Compositions of the invention include a hydroxy-functional polyester and a natural polymer. Articles can be made from such a composition so as to have sufficiently strong tensile strengths as to form disposable utensils or to have sufficient stretchability so as to form thin wrap films. However, the compositions are more environmentally friendly than commodity plastics such as polyethylene or polystyrene. Granular starches derived from a grain, a root, a legume, or mixtures thereof, are particularly preferred as the natural polymers for inclusion in the compositions.

Biodegradable formed article

Compositions of the invention include particular hydroxy-functional polyesters and a natural polymer. Among articles that can be made from such compositions are those with sufficiently strong tensile strengths as to form disposable utensils. However, the compositions are more environmentally friendly than commodity plastics such as polyethylene or polystyrene. Starches are particularly preferred as the natural polymers for inclusion in the compositions.
