Abstract:
Compositions and methods for reducing the decomposition rate of polymeric bioadhesives and viscosity enhancers, such as poly(acrylic acids). The compositions include at least one strong, stable chelating agent, preferably an organophosphorous compound such as diethylene triamine penta(methylene phosphonic acid). These biocompatible compositions are especially useful in the ophthalmic field.
Abstract:
Described is a process for the production of a library from a plurality of different units consisting of a solid or semisolid carrier (bead), a synthetic ligand and a binary information structure (tag), by means of which the building blocks of the ligand are coded, and the use of that library for searching for novel classes of active ingredient and individual active ingredients. Also described are compounds found using that process. The process is characterized by the use of element atoms or ions as binary tags which are bound non covalently to the beads. Their unique combination which can be measured by e.g. mass spectrometry codes for the specific ligand.

Abstract:
Process for increasing the sun protection factor of cellulosic fibre materials by treating the cellulosic fibre materials with at least one direct dye and at least one UV absorber.
Abstract:
A casting device with which, by introducing a thermocurable plastics into a heatable casting mould (1), the plastics is thermally cured in that casting mould at least to such a degree that a casting moulded in that manner can be released from the mould, comprises a reservoir for the thermocurable plastics and a feed means for feeding plastics from the reservoir into the casting mould (1), which mould has an inlet opening that extends at least along a substantial portion of the length of the casting to be moulded, wherein the casting device comprises a separate adapter (2) in which the feed means (20, 221, 23) for the plastics is arranged and which can be connected to the casting mould (1) in such a manner that, when the adapter (2) has been connected, an outlet opening (23) provided in the adapter (2) is arranged sealed to and substantially congruent with the inlet opening of the casting mould (1).
Abstract:

Abstract:
A process for the preparation of nucleoside diphosphate and triphosphate sugars wherein hydroxyl protective groups are removed enzymatically, and a process for the preparation of these sugars, which comprises coupling a nucleotide with a sugar-1-phosphate activated with a carbonyl bisazole and then removing the hydroxyl protective groups enzymatically.
Abstract:
The invention relates to a novel process for the production of tinted mouldings, in particular tinted contact lenses, in which a crosslinkable tinted polymer comprising units containing a crosslinkable group and units containing a reactive dye radical is crosslinked in solution, and to tinted mouldings, in particular tinted contact lenses, obtainable by this process. The present invention likewise relates to novel crosslinkable tinted polymers comprising units containing a crosslinkable group and units containing a reactive dye radical which can be employed in the novel process, in particular derivatives of a polyvinyl alcohol having a molecular weight of at least about 2000, to crosslinked tinted polymers, either homopolymers or copolymers, made from these novel crosslinkable tinted polymers containing a reactive dye radical, a process for the preparation of the novel crosslinkable tinted polymers comprising units containing a crosslinkable group and units containing a reactive dye radical and the homopolymers and copolymers obtainable therefrom, to tinted mouldings made from said homopolymers or copolymers, in particular tinted contact lenses made from these homopolymers or copolymers, and to a process for the production of tinted contact lenses using said homopolymers or copolymers.
