  • Stabilization of organosiloxanes containing SiOC-bonded radicals
    Patent number: 5274154
    Abstract: A process for stabilizing organosiloxanes containing SiOC-bonded radicals, by treating the organosiloxanes with compounds which scavenge hydroxyl groups, selected from (a) organic isocyanates, (b) compounds of the general formulaX.sub.m SiR.sub.n, (I)in which X represents a radical of the general formulaR.sup.1 COO-- (II)or a radical of the general formulaRR.sup.1 C.dbd.N--O-- (III)where R represents an optionally halogen-substituted C.sub.1 to C.sub.16 -hydrocarbon radical, R.sup.1 is the same as R or a hydrogen atom, m is 1, 2, 3 or 4, n is 0, 1, 2 or 3 and the sum of m+n=4, and mixtures thereof.
    Type: Grant

    Assignee: Wacker-Chemie GmbH
    Inventors: Michael Roth, Gunter von Au, Christa Blumlhuber, Richard Weidner, Edgar Schmidt, Christian Solbrig
  • Preparation and processing of mixtures containers organocyclosiloxanes
    Patent number: 4888405
    Abstract: The invention relates to a process for treating organocyclosiloxane-containing mixtures with condensation catalysts. The resultant mixtures can be reacted with silanes or siloxanes to form organopolysiloxanes containing functional groups.
    Type: Grant
    Filed: August 10, 1988
    Date of Patent: December 19, 1989
    Assignee: Wacker-Chemie GmbH
    Inventors: Norbert Gamon, Christian Solbrig, Karl Braunsperger
  • Process for preparing organopolysiloxane modified organic polymers
    Patent number: 4368294
    Abstract: Organopolysiloxane modified organic polymers are prepared by reacting organic polymers containing C-bonded hydroxyl groups with organopolysiloxanes containing Si-bonded hydroxyl groups and/or alkyl groups which are bonded to silicon via oxygen in the presence of water in excess of any formed during the reaction.
