    摘要: Bonded textile sheet materials having improved water vapor absorbency can be manufactured by bonding the sheets with polymeric binders and additionally impregnating these sheets with glycidyl ethers, chlorohydrin compounds corresponding thereto and/or reaction products of the chlorohydrin compounds with compounds containing NH groups, and drying the impregnated sheets at elevated temperatures and at the same time fixing the impregnants by means of compounds containing NH groups.

    摘要: Enzymes are immobilized by mixing the following components with one another in aqueous solution:(a) an enzyme or a dispersed microorganism,(b) a water-soluble glycidyl ether, prepared by subjecting from 1 to 30 equivalents of an epoxide of the formula I ##STR1## where R.sup.1, R.sup.2 and R.sup.3 are each hydrogen, methyl or ethyl, to an addition reaction with 1 equivalent (based on OH groups) of a polyfunctional alcohol of 2 to 6 carbon atoms or of a mono- or disaccharide to produce an adduct, reacting the adduct with epichlorohydrin and, if required, then carrying out cyclization to give the epoxide, and(c) a water-soluble amine possessing two or more NH groups, if necessary in a partially neutralized form,and allowing the mixture thus obtained to gel.
