AQUEOUSLY DISPERSIBLE POLYURETHANE |
| 摘要 |
The invention relates to an aqueously dispersible polyurethane having a specific amount of silicon n(Si)/m(PU) of from 0.05 mol/kg to 1 mol/kg, and a specific amount of urea groups, n(U)/m(PU), >N—CO—N< of from 0.8 mol/kg to 2 mol/kg, wherein in each case the specific amount of substance is calculated as the ratio of the amount of substance n of the entity under consideration, to the mass m(PU) of the polyurethane, to a process for the preparation thereof, and a method of use thereof. |

1. An aqueously dispersible polyurethane having
(aa) a specific amount of silicon n(Si)/m(PU) of from 0.05 mol/kg to 1 mol/kg, and (cc) a specific amount of urea groups, n(U)/m(PU),
>N—CO—N< (formula I) of from 0.8 mol/kg to 2 mol/kg,wherein in each case the specific amount of substance is calculated as the ratio of the amount of substance n of the entity under consideration, i. e. atoms such as Si and C, and groups of atoms such as >N—CO—N< and —OH, to the mass m(PU) of the polyurethane. |
