Abstract: MICROPOROUS SHEET STRUCTURES ARE PREPARED BY CONVERTING AQUEOUS DISPERSIONS OF POLYURETHANE POLYMERS HAVING SALT-TYPE GROUPS INTO SHEET STRUCTURES AND MELT SINTERING THE STRUCTURES. THE DISPERSIONS ARE SEDIMENTING AND REDISPERSIBLE, THE PARICLES HAVING AN AVERAGE PARTICLE SIZE ABOVE ABOUT 5U. THE PRODUCTS OF THE INVENTION ARE USEFUL AS ARTIFICAL LEATHER IN THE PREPARATION OF RAINCOATS, HANDBAGS, BELTS, SHOES, UPHOLSTERY AND ALSO AS VIBRATION AND SOUND DAMPING MATERIALS.

Abstract: Coarse, aqueous dispersions of polyurethanes that sediment but are capable of being redispersed are prepared from 40 to 99.5 percent by weight of a polyurethane polymer having a molecular weight greater than 5,000 and preferably above 20,000 which is free of salt-forming groups and from about 0.5 to about 60 percent by weight of a polyurethane polymer containing saltforming groups. Salt formation is permitted to occur until 0,0007 to 0,011 equivalent percent has taken place and the mixture is then dispersed at least in a quantity of water such that the solids content is 60 percent.
Abstract translation: 沉淀但能够再分散的聚氨酯的粗分散水分散体由40至99.5重量％的分子量大于5,000，优选20,000以上的不含成盐基团的聚氨酯聚合物和约0.5重量％ 至约60重量％的含有成盐基团的聚氨酯聚合物。 允许产生盐形成直到发生了0,700至0,011当量百分比，然后混合物至少以一定量的水分散，使得固体含量为60％。

Abstract: The present invention is concerned with a process for preparing aqueous dispersions from solid polymer precursors which are polyester or polyurethane oligomers containing both hydrophilic centers and cross-linking sites and subsequently coating substrates with the thus obtained dispersions. The aqueous dispersion is applied to a substrate and dried with resultant cross-linking of the film.

Abstract: A mortar comprising an inorganic binder such as anhydrite, gypsum or cement is rendered more flowable and processible by incorporating therein a sulfonic acid group-containing formaldehyde condensation product with a cycloalkanone, e.g. preferably about 0.05 to 5% by weight of the binder of the condensation product of sodium sulfite, formaldehyde and cyclohexanone. There may also be present an auxiliary such as FeSO4,7 H2O,Al2(SO4)3.18 H2O or KAl(SO4)2, as well as an additive such as a plasticizer, hardening accelerator, retarder, air-entraining agent, thickener, activator, anti-foam agent or synthetic resin dispersion, and/or an aggregate such as sand, silica, perlite, pumice or foamed plastic beads.
