| titleOfInvention | Process for the preparation of an aqueous dispersion of organopolysiloxane |
| abstract | In the present invention, as a method for producing an organopolysiloxane aqueous dispersion,n n n (a) reacting an organopolysiloxane (1) of formula (I) comprising a condensable group with silane (2) of formula (II) or a hydrolyzate thereof in the presence of water (3) and an emulsifier (4) ,n n n [Formula I]n n n R 1 O (R 2 SiO) x R 1 n n n [Formula II]n n n (R 3 O) 3 SiCR 2 2 -Yn n n [Wherein,n n n R is a monovalent hydrocarbyl radical having 1 to 18 carbon atoms,n n n R 1 is a hydrogen atom or an alkyl radical having 1 to 8 carbon atoms,n n n x is an integer from 10 to 1100,n n n R 2 is a hydrogen atom or a monovalent alkyl radical having 1 to 4 carbon atoms,n n n R 3 is an alkyl radical having 1 to 8 carbon atoms per radical,n n n Y is of the formula -NHR 4 , -NR 4 2 or Wherein R 4 is a monovalent hydrocarbyl radical of 1 to 18 carbon atoms, optionally containing nitrogen and / or oxygen atoms,n n n R 5 is a divalent hydrocarbyl radical of 3 to 12 carbon atoms optionally containing nitrogen and / or oxygen atoms;n n n (b) optionally adding an aqueous silica dispersion (5) mixed with silane (2) of formula (II) during or after reaction (a),n n n (c) optionally, adding an adhesion promoter (6) during or after reaction (a), andn n n (d) optionally adding additional material (7) that does not participate in reaction (a) during or after reaction (a)n n n Including;n n n Provided that the metal-containing catalyst should not be used and that the organopolysiloxane (1) and silane (2) should be used in an amount such that upon removal of water (3) the organopolysiloxane forms an elastomeric film insoluble in toluene. This is disclosed. |
