Abstract: A solution system for biopolymers in the form of carbohydrates based on a molten ionic liquid, additives optionally being contained in the solution system, is described. This solution system contains a protic solvent or a mixture of several protic solvents, and in the case where the protic solvent is solely water, this is present in the solution system in an amount of more than about 5 wt. %. Carbohydrates can be incorporated into the solution system, in particular in the form of starch, cellulose and derivatives thereof, and it can then be used for regeneration of the carbohydrates contained therein. A particularly advantageous process for the preparation of the solution system containing the carbohydrates and for the preparation of regenerated carbohydrates, in particular in the form of regenerated cellulose fibers, is moreover described. The invention accordingly also provides such spun fibers as are distinguished in that they are non-fibrillating. The invention offers in particular economic advantages over the systems of the prior art.

Abstract: Reducing adhesiveness of a molded body from polymer, comprises contacting polar solvents on the surface of polymer in the absence of non-polar solvent, where the polar solvent is hydroxylgroup containing compound, and/or carbonylgroup containing compound, and the polar solvent do not contain non volatile salt-like or polymer character ingredients; and gluing an essential portion of the polar solvent and/or their mixture on the surface of the molded body. Reducing adhesiveness of a molded body from polymer, comprises contacting polar solvents on the surface of polymer in the absence of non-polar solvent, where the polar solvent is hydroxylgroup containing compound of formula (R1>-(O-A)n-OH), and/or carbonylgroup containing compound of formula (R2>-CO-X-R3>), and the polar solvent do not contain non volatile salt-like or polymer character ingredients; and gluing an essential portion of the polar solvent and/or their mixture on the surface of the molded body. R1>, R2>2-20C alkyl, 2-20C alkenyl, 5-20C cycloalkyl, 6-20C aryl, 20C alkylaryl or 20C arylalkyl; A : 2-4C alkylene; n : 0-10, preferably 0; X : O, S or chemical bond (if R2> is not hydrogen); and R3>1-20C alkyl, 1-20C alkenyl, 5-20C cycloalkyl, 6-20C aryl, 6-20C alkylaryl or 6-20C arylalkyl.

Abstract: The present invention is related to the use of specific cyclic and/or polymeric aryl-phosphines as flame retardants and to a method for reducing the flammability of organic material by incorporating into the material these specific cyclic and/or polymeric phosphines. Moreover, the invention is related to a polymeric composition containing a polymeric material and at least one of the specific cyclic and/or polymeric phosphines in an amount of from 1 to 15% by weight, based on the weight of the polymeric material. The invention also relates to a composition comprising at least one of the specific cyclic and/or polymeric phosphines and at least one polymerizable monomer.
