| titleOfInvention | Method for the preparation of polymethylphenylhydroxysiloxanes |
| abstract | A method for the production of polyimiethyleenylhydroxyslloxynes, consisting in hydroitinous ^ c ^^ oiU ^ omdensationndimethyldichlorosilane and Oenyltrichlorosilane in the presence of hydrogen chloride acceptors are usednin an amount necessary to neutralize the hydrogen chloride evolved in the form of a suspension during the reactionnin an organic solvent followed by separation of the resulting solution of prlimctylOenylrhydroxysiloxanesnin an organic solvent from chloride precipitate also formed in the reaction andnisolating polymethyl-oenylhydroxysiloxanes by distilling off the solvent and low-molecularncyclic siloxanes, characterized in that the mixture is subjected to hydrolytic cross-polymerizationndimciylrdichlorosilane and Oenyltrichlorosilane containing 5 - 50 moles of dimethyldichlorosilane per 1 mole of Oenyltrichlorosilane,nwherein the copolycondensation reaction is carried out at a temperature of 20-60 ° C in the presence ofnsuspensions of hydrated calcium or aluminum oxide or hydroxide in an aliOatic or aromatic solvent,ncontaining 100 - 200 parts by weight of water per 100 parts by weight of oxide or hydroxide,na solution of polSmeiylrOenylhydroxyslrxanes formed as a result of the reaction, after separation of the chloride from the sludgencalcium or aluminum is distilled under reduced pressure at temperatures up to 200 ° C |
