The invention relates to a biodegradable chewing gum comprising one or more conventional chewing gum components and as gum base at least one biodegradable polymer selected from the group of polyesters and polycarbonates.

Biodegradable chewing gum

A surgical filament produced by spinning a mixture of polylactides and additive.

Filament material polylactide mixtures

An approximately 1 to 6 wt. % solution manufactured from polyethylene with a molecular weight M.sub.w of at least one million and a solvent is extruded into a spinning duct at an extrusion temperature T.sub.E =180.degree. to 250.degree. C. at an extrusion rate V.sub.E =5 to 150 m/min. The duct is kept at a temperature of 100.degree. to 250.degree. C. by means of a heating device below the jet outlet area. The fibers are drawn off at a rate V.sub.w of at least 500 m/min, preferably 1500 to 4000 m/min, and freed of the solvent without further stretching. The fibers obtained are especially well suited for manufacturing industrial yarns, protective clothing, bulletproof vests, ropes, and parachutes. In the form of staple fibers, they are suitable for reinforcing various plastics.
