A method for preparing a thermoplastic polyoxazolidone, the method including catalytically reacting one or more aromatic diisocyanates and one or more diepoxides, wherein the one or more diepoxides comprise one or more 2-phenylpropane-1,3-diol diglycidyl ether derivatives. The one or more diepoxides further contain one or more diglycidyl ethers of aromatic diols.

Thermoplastic polyoxazolidones from diisocyanates and diglycidyl ether of 2-phenyl- 1,3-propanediol derivaitives

The present invention relates to the polyamines N,N'-diaminopropyl-2-methyl-cyclohexane-1,3-diamine and N,N&#x2032;-diaminopropyl-4-methyl-cyclohexane-1,3-diamine and mixtures thereof, to the use thereof as curing agents for epoxy resin and to a curable composition comprising epoxy resin and these polyamines. Even at low temperatures this curing agent/the corresponding curable composition cures rapidly and is early-stage water resistant and is thus especially suitable for floor coatings. The invention further relates to the curing of this composition and the cured epoxy resin obtained by curing of this composition.

Purification of ionic liquids

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.
