Soluble

high molecular weight （MW） and ladderlike polyphenylsilsesquioxane （LPPSQ） and its copolymers

ladderlike random and block copolymethyiphenylsilsesquioxanes（LR-PMPSQ and LB-PMPSQ）have been prepared by preamminolysis

hydrolysis and polycondensation reactions. The preparation method can be carried out easily at the temperature below 95℃with high yield of 95 %

instead of the conventional way by using high-boiling solvent and any reaction activator or by precipitation with methanol. Three kinds of ladderlike polymers have been characterized. The MW’s of the polymers reached to 10

without noticeable gelling. The scheme for synthetic route has been proposed.
