with tetrachlorosilane

Steps:

2 EXAMPLE 2

EXAMPLE 2 0.1 mol (17 g) tetrachlorosilane and 0.4 mol (37.8 g) dimethylchlorosilane were cohydrolyzed and condensed using the procedure described hereinbefore in Example 1. The product, tetrakis(dimethylsiloxy)silane STR9 was collected at 52° C. under a pressure of 0.8 kPa in 55% yield. Using DSC, the melting point is measured at -108° C. 1.13 g (3.44 mmol) of this silane and 5.0 g (15.14 mmol)p-allyloxy-p'-diphenylbenzoate were then reacted using the procedure described hereinbefore in Example 1.
