    摘要: Organosiloxane amine copolycondensates as statistic or block copolycondensates or mixtures thereof consisting of the units ##STR1## in which R.sup.1 to R.sup.5 is ##STR2## and R.sup.6 is bound directly to the nitrogen atom or the double-bonding X group and is alkylene, cycloalkylene or ##STR3## in which n is 1 to 6 and m 0 to 6. The free valences of the oxygen atoms bound to the silicon atom are saturated by silicon atoms of further groups of formula III, optionally with the inclusion of cross-linking agents, X stands for ##STR4## in which R" is H or alkyl. In addition, preparation methods and the use of the products for the removal of dissolved metals from liquid phase or for the adsorption of gaseous compounds.

    摘要: There is prepared an aqueous suspension which in addition to water, consists of 2 to 50 weight % of a mixture of bentonite and inorganic fibers, with the portion of inorganic fiber being 1 to 30 weight % and the portion of bentonite being 1 to 30 weight % and wherein the total amount of solids does not exceed 50 weight %. With the suspension there is attained an improvement of the mechanical properties of thermal insulating molded objects which are employed for thermal insulation and which for example, contain pyrogenically produced silica as a filler by delivery of this suspension on the thermal insulating plate. The suspension can also be delivered on thermal insulating molded bodies on which there is pressed a fiber net or a fiber felt. After applying the suspension several thermal insulating molded bodies can be joined together where the coating formed consisting of bentonite and inorganic fibers acts as binder. The heat insulating molded article in addition to this layer, can have one or more additional coatings based on organic or inorganic lacquer systems, silicone compositions or low melting glazes.
