| abstract | 1,101,644. Polyurethane solutions. KURASHIKI RAYON KABUSHIKI KAISHA. 4 Feb., 1965 [7 Feb., 1964; 18 Feb., 1964], No. 4986/65. Heading C3R. [Also in Division D1] Polyurethanes and compositions used in non- woven fabrics (see Division D1) are: (Example 1) polyurethane derived from polyethylenepropylene adipate having hydroxyl groups at both ends, p,p<SP>1</SP>-diphenylmethane diisocyanate and ethylene glycol is dissolved in dimethylformamide; (Example 2) polyurethane derived from poly-epsilon-caprolactone, having hydroxyl groups at both ends, p,p<SP>1</SP>-diphenylmethane diisocyanate and ethylene glycol is dissolved in tetra-hydrofurane; (Example 3) a prepolymer having isocyanate groups at both ends and derived from polytetramethylene glycol, p,p<SP>1</SP>-di-phenylmethane diisocyanate and p,p<SP>1</SP>-methylene-dianiline is dissolved in dimethylformamide; (Example 4) ethyl-celluloseoctadecylurethane is added to the solution of Example 1; (Example 5) sorbitan monopalmitate is added to the solution of Example 2; (Example 6) the solution of Example 3 is diluted with dimethylformamide and ethylcelluloseoctadecylurethane is added; (Example 7) polyurethane derived from polyethylene adipate, diethylmethane diisocyanate and 1,4-butandiol and sorbitan monostearate are dissolved in dimethylformamide; another solution has the same composition but contains also stearyl alcohol; and (Example 8) a polyurethane formed from the same monomers as in Example 1, but in different proportions, is dissolved in dimethylformamide and mixed with sorbitan monostearate. |
