Method of making organo-silicon polymers having mono- and tetra-functional siloxane units. |
摘要 |
<p>There is disclosed a method for making organo-silicon polymers from alkyldisiloxanes and alkylsilicates wherein the alkyl groups of the disiloxanes have two or more carbons. Gelling of the organo-silicon polymers is avoided by; first mixing the disiloxane with the alkylsilicate and adding thereto a strong protic acid; and, after reaction has occurred in the aforementioned mixture, adding thereto, in a drop-wise manner, a solution of hydrochloric acid.</p> |
