Abstract

1326161 Hydrophilic polyurethane foam BAYER AG 13 Jan 1971 [2 Feb 1970] 1651/71 Heading C3R Hydrophilic polyurethane foam having a density of 6-20 Kg./m.<SP>3</SP> is prepared by reacting: (a) one or more polyisocyanates, (b) water, (c) a polyol mixture of (I) at least one aliphatic or cycloaliphatic polyol of M.W. up to 500 and (II) at least one polyol having M.W. 500-5000. From 5-50 parts by weight of water are used per 100 parts by wt. of (c). I comprises 5-17À6% by wt. of the total of (a)+(b)+(c). The amount of polyisocyanate used is 20-80% of that theoretically required for reaction with (a)+(b). I may be diethylene glycol and/or 1,1,1-trimethylolpropane. In all the examples II is a polyether of ethylene diamine and propylene oxide mixed with a polyether of 1,1,1-trimethylolpropane and propylene oxide and/or a polylester of adipic acid, phthalic acid, glycerol and 1,1,1-trimethylolpropane. The polyisocyanate exemplified is polyphenylpolymethylenepolyisocyanate. Additional blowing agents, activators and/or stabilizers are also added.
