| Abstract: | Two efficient methods for the preparation of polydimethyl-diphenylsiloxane diolhave been described. Using LiOH as catalyst, DMF as promoter, octamethylcyclotetrasiloxane and octapheny- lcyclotetrasiloxane as monomers,under certain conditions,the polymerization reaction was carried out and molecular weight of the copolymers obtained can be controlled by the amount of water or lithium hydroxide added. Thecopolymers have been purified by treating the raw products with petroleum ether andmethanol. |
