| titleOfInvention |
Method for the preparation of a low-impurity organopolysiloxane by the polymerization of an organopolysiloxane oligomer |
| abstract |
The invention provides a novel method for the neutralization of the residual alkali catalyst following alkali-catalyzed polymerization of an organopolysiloxane oligomer to produce a high-polymeric organopolysiloxane, according to which the organopolysiloxane after completion of the polymerization reaction is admixed with a trihydrocarbyl monohalosilane, e.g. trimethyl chlorosilane, and a hexahydrocarbyl disilazane, e.g. hexamethyl disilazane, in combination as the neutralizing agent so that the neutralization is very complete and still the product organopolysiloxane contains very little impurities of alkali and halogen. |
