Polyurethane foams

Abstract

The invention relates to polyurethane foams comprising (i) ethylenimine, polyethylenimine, polyvinylamine, polyvinylamine copolymers, carboxymethylated polyethylenimines, phosphonomethylated polyethylenimines, quaternized polyethylenimines and/or dithiocarbamatized polyethylenimines or (ii) alkali metal hydroxides and/or alkaline earth metal hydroxides or a mixture of (i) and (ii).

1 . A composition, comprising: 
 a polyurethane foam and a component which is:    (i) ethylenimine, polyethylenimine, polyvinylamine, polyvinylamine copolymers, carboxymethylated polyethylenimines, phosphonomethylated polyethylenimines, quaternized polyethylenimines dithiocarbamatized polyethylenimines or a mixture thereof,    (ii) alkali metal hydroxides, alkaline earth metal hydroxides, or a mixture thereof, or    (iii) a mixture of (i) and (ii).    
     
     
         2 . The polyurethane foam as claimed in  claim 1 , comprising component (i), wherein (i) is covalently bound to the polymer of the foam.  
     
     
         3 . The polyurethane foam as claimed in  claim 1 , in which component (ii) is sodium hydroxide, potassium hydroxide, or a mixture thereof.  
     
     
         4 . The polyurethane foam as claimed in  claim 1 , which contains from 0.1 to 80% by weight of (i), (ii), or a mixture thereof, based on the weight of the foam.  
     
     
         5 - 9 . (canceled)  
     
     
         10 . A shaped body, comprising the composition of  claim 1.
