| titleOfInvention | Method for producing isocyanate group-containing organopolysiloxane |
| abstract | (57) [Summary] (Modified) [Object] The present invention provides an organopolysiloxane having one isocyanate group in the molecule by the reaction of an organopolysiloxane having one primary amino group in the molecule with phosgene. It is an object of the present invention to provide a method for producing a polysiloxane with high yield and high purity. The method for producing an isocyanate group-containing organopolysiloxane according to the present invention has a general formula: [Here, R 1 is a monovalent organic group having 1 to 8 carbon atoms, R 2 , R 3 and R 4 are monovalent organic groups having 1 to 8 carbon atoms or a siloxy group represented by -SiOR 5 R 6 R 7 ( R 5 , R 6 and R 7 are monovalent organic groups having 1 to 8 carbon atoms), n is an integer of 1 to 10 and a is 0, 1 or 2] and one primary amino group in the molecule. Phosgene is allowed to act on an organopolysiloxane containing a compound of the general formula: (R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , a and n are the same as above) It is characterized by obtaining an organopolysiloxane containing one isocyanate group in the molecule represented by. |
