Polyurethane solutions

A process for the production of polyurethane solutions by reaction of a diisocyanate with a mixture of a glycol and a polymer bearing terminal hydroxy groups in a solvent medium under certain prescribed conditions. The resulting polyurethane solutions are especially valuable as impregnants or coatin...

Zusammenfassung:	A process for the production of polyurethane solutions by reaction of a diisocyanate with a mixture of a glycol and a polymer bearing terminal hydroxy groups in a solvent medium under certain prescribed conditions. The resulting polyurethane solutions are especially valuable as impregnants or coating agents for textile substrates, for example in the preparation of a microporous synthetic leather.
