Process for producing microporous vapor-permeable film or sheet |
| abstract |
Microporous, vapor-permeable films or sheets are produced by mixing in a solution of polymers comprising a polyurethane elastomer as the essential constituent, with stirring and, if necessary, heating, a compound (I) having at least two basic nitrogen atoms in the molecule and at least two active hydrogen atoms attached thereto and a compound (II) having at least three NCO-groups in the molecule; or a compound (III) having at least two basic nitrogen atoms in the molecule and at least three active hydrogen atoms attached thereto and a compound (IV) having at least two NCO-groups in the molecule, thereby immediately reacting the compound (I) with the compound (II) or the compound (III) with the compound (IV) to prepare a dispersion of colloid particles having contained therein the polymers comprising a polyurethane elastomer as the essential constituent, impregnating a substrate with said dispersion of colloid particles or coating said dispersion on a substrate, then subjecting the dispersion to wet coagulation to coagulate the dispersion and remove the solvent and then removing the coagulating liquid. |
