Samples of polyphenylsilsisquioxane （PPSQ）using CaF

or MgF

as the main catalysts hadbeen prepared under different polymerization conditions. The results were treated on anorthogonal design L

（3

）. All weight-average molecular weights （M

） of PPSQ had beenmeasured by gel permeation chromatography （GPC）. Effects of polymerization conditionsincluding reaction temperature

composition of the dual catalysts （CaF

or MgF

and DCC）

mixture of solvents and reaction time on M

of PPSQ have been discussed. The quantity of thecatalysts is the most important factor that affects M

of PPSQ. Reaction temperature is thesecond important factor. Appropriate polymerization condition has been established to get PPSQwith high M
