| titleOfInvention | Lignin-containing isocyanate prepolymer mixtures, processes for their preparation and their use for the production of polyurethanes and processes for the production of the polyurethanes |
| abstract | NCO-prepolymer mixt. (I) contg. urethane gps.and 2.5-30 wt.% reactive NCO is claimed. (I) is obtd. by reacting (a) 4,4'-, 2,4'- and 2,2'-di-phenylmethane diisocyanate, an isomer mixt. of 4,4'- and 2,4'-and opt. 2,2'-di-phenylmethane diisocyanate or a mixt. of diphenylmethane diisocyanates and poly-phenyl-polyphenylene polyisocyanates with (b) a suspension contg. (b-1) polyoxypropylene glycol(s) (IIA) and/or polyoxypropylene-polyoxyethylene glycol(s) (IIB) with a mol.wt. of 400-6000, pref. 1000-3000 and (b-ii) lignin. Also claimed are methods for producing (1) (I) by reacting the specified organic polyisocyanates and suspension; and (2) compact or cellular polyurethanes, pref. PU foam. |
