摘要:
The invention relates to a process for the production of polymers containing ammonium groups in which OH-functional polymers are first reacted with isocyanates corresponding to general formula IOCN--R--CH.sub.2 --X Iin which R represents C.sub.2-11 alkylene or arylene and X represents halogen, to form urethanes and the urethanes are subsequently reacted with tertiary aliphatic amines corresponding to formula II ##STR1## in which R.sup.1 to R.sup.3 may be the same or different.
摘要:
Water soluble, polymerizable binders suitable for surface coating contain co-condensed residues of at least two polyalkylene glycols with different molecular weights, an alkoxylated polyol, a polycarboxylic acid and an optionally substituted acrylic acid.
摘要:
The invention relates to a process for the production of carbonic acid esters of polysaccharides which is characterized in that polysaccharides are reacted with carbonic acid esters.
摘要:
The invention relates to certain highly substituted carboxymethyl sulfoethyl cellulose ethers (CMSEC), to a simplified and economic process for their production and to their use as thickeners in textile printing.
摘要:
The invention relates to a new class of water-soluble ionic cellulose derivatives and their use as additive for gypsum- and cement-containing compounds.
摘要:
The present invention relates to new amino and ammonium isocyanates, to a process for their preparation, e.g. by the reaction of certain ureas with isocyanates, and to the use of the new substances for the production of polymers containing ammonium groups.
