A starch fiber produced by a spinning process and comprising:

Starch-Containing fibers, process for their production and products made

A starch composition including destructurized starch, an acrylate copolymer having a molecular weight of more than 400,000, water, and additives such as plasticizers, lubricants, fillers, reinforcing agents, stabilizers, impact modifiers, and flame retardants. Also disclosed are a method of preparation thereof and articles produced therefrom. The compositions are readily usable on existing devices and can be thermoplastically processed substantially in accordance with methods currently in use.

Thermoplastically processible composition of starch acrylate copolymers

A biodegradable, single-phase starch/polymer mixture comprising

Starch/polymer mixture, process for the preparation thereof, and

A process for the production of a homogeneous, thermoplastically processible melt. The process includes a. introduction of chemically modified starch into an intake zone of an extruder and conveyance thereof to a receiving zone, b. addition of a prehomogenized liquid mixture of plasticizer, emulsifier, and additives, followed by mixing and further conveyance of the starch liquid mixture through the receiving zone at elevated temperature, c. destructurization of the modified starch without adding any water and conveyance of the starch and mixture at elevated temperature to form a homogeneous, thermoplastically processible melt, d. degassing of the melt at elevated temperature and under reduced pressure, and e. extrusion thereof through a die at elevated temperature and pressure.

Process and apparatus for producing starch melt and products obtainable

A composition having at least 50% by weight polyamide and a liquid crystalline polymer capable of forming an optically anisotropic melt above 200.degree. C. Such compositions are transformed by deformation at temperatures below the melting point and above the glass transition temperature of the polyamide. Shaped bodies made thereby have excellent tensile strength and elongation at break characteristics.

Process for the production of shaped articles

Heat-resistant, polymer-containing, solvent-free adhesive compositions are prepared by reacting a novel mixture of saturated polyester or copolyester with capped isocyanate under the influence of temperature and, if necessary, catalysts, with evident viscosity increase, with cross-linking as appropriate. The adhesive compositions combine the process-technical properties of low-viscosity melt-adhesives and the strength, tenacity and stability of cross-linked duroplasts or high-viscosity thermoplasts. Subsequent working and protection from explosion are not necessary. Use is possible in each known art for melt-adhesives, e.g. as paste, powder, melt, textiles, or flat structures. In addition, the compositions are suitable as melt coatings or for injection moulding reactions.
