Method for the preparation of a silicon-containing polysulfide-type polymer |
摘要 |
To provide a highly efficient and stable method for the preparation of a silicon-containing polysulfide-type polymer, in particular, a polysulfide-type polymer with organosilyl groups, the method being carried out without generation of by-products that could have high impact on the environment. A method for the preparation of a silicon-containing polysulfide-type polymer characterized by mixing (A) a silicon-containing compound having a silicon atom-bonded monovalent organic group having an aliphatic unsaturated bond; (B) a polysulfide polymer with at least two mercapto groups in one molecule; and (C) an organic base or ammonia; the mixing being carried out in the presence of (D) sulfur.
