| titleOfInvention | Polyurethane polymers and process for their preparation |
| abstract | A polyurethane is obtained by reacting a polyoxalkylene alkyl glocoside with an organic polyisocyanate. The alkyl glucoside may be the methyl, ethyl, propyl or butyl derivative and preferably 2-90 mols. of ethylene oxide or propylene oxide is used per mol. of alkyl glucoside at a temperature of 200-400 DEG F. in the presence of an alkaline catalyst, to give a derivative having a molecular weight of 300 and 5000. Specified polyisocyanates are the toluene and tolylene disocyanates. A cellular product may be obtained by reacting in the presence a blowing agent, such as trichlorofluoromethane, an amine catalyst such as tetramethyl butane 1,4-diamine, or triethylene diamine, together with stannous octoate. A silicone emulsifier, lecithin and N-ethylmopholine may also be used. |
