Description

Compositions based on diisocyanates from renewable raw materials

The invention relates to compositions based on 2,5-diisocyanato-1, 4: 3,6-dianhydro-2,5-dideoxy-D-mannitol (I), 2,5-diisocyanato-1, 4: 3,6 Dianhydro-2,5-dideoxy-D-glucitol (II) and / or 2,5-diisocyanato-1,4: 3,6-dianhydro-2,5-dideoxy-L-iditol (III), alone or in any mixtures.

Renewable raw materials refer to agricultural and forestry-produced products that are not used as food or feed. They are used materially, but also for the production of heat, electricity or fuels.

Polyurethanes from customary isocyanates known in polyurethane chemistry and 1: 4 - 3: 6 dianhydrohexitols are known from US 4,443,563 and DE-OS 31 11 093. Disadvantage is the restriction to Dianhydrohexitole, what the

Lack of variation in today's conventional polyols and polyol blends.

Also known are polyurethanes starting from diamino-dianhydro-dideoxy-hexitols (J. Thiem in Makomol, Chemie 187, 2775 - 2778, 1986). However, the procedure described here requires phosgene or

Phosgene substitutes, which due to their toxicity a considerable

require procedural effort.

Furthermore, polyurethanes of certain monoisocyanates based on 1: 4 - 3: 6 dianhydrohexitols are known (Thiem, J., et al., Macromol Rapid Comman., 19, 21-26, 1998). Such homopolymers, in which the isocyanate building block and the polyol block are almost identical, offer no variation in the

Material properties and are therefore not used commercially today.

Polyurethanes and polyureas from certain diisocyanates of 1: 4 - 3: 6 dianhydrohexitols and a short-chain diol - 1, 4-butanediol - and a

short-chain diamine-1,4-diaminobutane-as well as 1,4-butanedithiol are known (Thiem, J., et al., Macromol. Chem. Phys., 202, 3410-3419, 2001). However, such compounds are not of technical and industrial relevance. The restriction to a single monomer, which also carries neither ester nor carbonate groups, leads to a very limited range of variation of the properties. Therefore, you will find almost no applications today.

The object of the invention was to find new compositions based on diisocyanates and polyisocyanates from renewable raw materials.

The object has been achieved according to the patent claims and the description.

The invention relates to compositions essentially comprising a reaction product of
