Biodegradable compositions of synthetic and natural polymers
A biodegradable interpolymer and composition is prepared by the reactive blending of a synthetic polymer having functional groups with a naturally occurring biodegradable polymer such as a protein compound. During reactive blending, the synthetic polymer can undergo a chemical reaction with the biodegradable natural polymer which results in covalent and physical bonding between the two polymers, thereby forming an interpolymer. By this process, a biodegradable interpolymer composition is produced that is suitable for moulding various articles.

Biopolymer optical waveguide and method of manufacturing the same
A method of manufacturing a biopolymer optical waveguide includes providing a biopolymer, unwinding the biopolymer progressively to extract individual biopolymer fibers, and putting the unwound fibers under tension. The tensioned fibers are then cast in a different polymer to form a biopolymer optical waveguide that guides light due to the difference in indices of refraction between the biopolymer and the different polymer. The optical fibers may be used in biomedical applications and can be inserted in the body as transmissive media. Printing techniques may be used to manufacture the biopolymer optical waveguides.

Process for fixing images in plastics, adhesive layer and fixed image
A method for fixing images in plastic moldings which allows images to be fixed in a plastic molding in such a way that the image is embedded therein and does not experience lasting changes, even for elastic plastic moldings. To avoid loss of image quality when the image is transferred into the plastic molding, the method for fixing images in plastic moldings after generating an image on an adhesive layer is characterized in that an image receptor layer of liquid plastic is applied to the image which, with or without an additional carrier, is generated on the adhesive layer. Components of the adhesive layer are at least partially miscible with the liquid plastic when it is applied. The liquid plastic phase is then converted to a solid plastic phase.
