  • Patent number: 11845914
    Abstract: Low molecular weight silicone copolymers prepared by reacting an oxamido ester-terminated silicone with a polyetheramine and a primary or secondary amine are useful in treating fabrics to obtain a soft hand and also hydrophilicity, and can be prepared without the use of highly toxic reagents.

    Inventors: Thomas Lehotkay, Walter Eichberger, Oliver Schaefer, Inge Seeger-Feichtinger
  • Patent number: 5693734
    Abstract: Organosilicon compounds containing furanyl groups which contain units of the formula ##EQU1## in which R is identical or different and is a hydrogen atom or monovalent, SiC-bonded, aliphatically saturated, optionally substituted hydrocarbon radical, which can be interrupted by oxygen atoms,R.sup.1 is identical or different and is an optionally substituted hydrocarbon radical having 1 to 8 carbon atoms, which can be interrupted by 1 to 3 oxygen atoms.A is identical or different and is an SiC-bonded furanyl radical of the formula ##STR1## where R.sup.2 has the meaning given above for the radical R and R.sup.3 is a divalent hydrocarbon radical having 2 to 30 carbon atoms, which can contain one or more groups, chosen from the group consisting of ##STR2## a is 0, 1, 2 or 3, b is 0, 1 or 2 andc is 0, 1 or 2,with the proviso that the sum a+b+c is less than or equal to 3 and the organosilicon compound contains at least one radical A per molecule.

  • Patent number: 5525696
    Abstract: Compositions which comprise(A) a polymeric organosilicon compound having 1 to 6 Si-bonded hydrogen atoms per molecule,(B) a polymeric organosilicon compound having at least two alkenyl groups per molecule and a viscosity of not more than 100 mm.sup.2 /s,(C) a polymeric organosilicon compound having on average at least 10 Si-bonded hydrogen atoms per molecule,(D) a catalyst and, optionally(E) an inhibitor,with the proviso thatthe molar ratio of all the Si-bonded hydrogen atoms to all the SiC-bonded alkenyl groups in the composition is on average less than 1,the composition comprises (B) in an amount such that the composition comprises on average at least 1.1 alkenyl radicals of (B) per Si-bonded hydrogen atom of (A)and the content of Si-bonded hydrogen atoms of (C) is 5% to 50%, based on the number of all the Si-bonded hydrogen atoms present.
