POLYMERIZATION OF POLYDIORGANOSILOXANE IN THE PRESENCE OF FILLER |
摘要 |
A method of polymerizing hydroxyl-endblocked polydiorganosiloxane in the presence of filler, including acidic filler such as fumed silica, through the use of basic diorganosilanolates as catalysts is claimed. Preferred diorganosilanolates are tetra-n-butylphosphonium dimethylsilanolate and potassium dimethylsilanolate. The silicone polymer-filler mixture produced is useful in silicone greases and elastomers. Methods of combining the silicone polymer-filler mixture with various curing agents to yield curable compositions are claimed. |
