Versuchsvorschrift
Comparative Example 4. (Reaction between Divinyldisiloxane and Dimethylmethoxysilane) A glass tube was filled with 0.186 g of 1,3-divinyltetramethyl-1,3-disiloxane, 0.18 g of dimethylmethoxysilane, and 0.047 g of toluene. The contents were combined with 2 μL of a toluene solution of a complex of 1,3-divinyltetramethyldisiloxane and 0-valence platinum (platinum content: 0.4 Wt. %). The content was heated for 3 hours at 50° C. Gas chromatography analysis showed that the conversion of 1,3-divinyltetramethyl-1,3-disiloxane was 68% and that monosilyl and disilyl compounds of divinylbenzene were produced with the yields of 37% and 30%, respectively. The ratio of α-adducts to β-adducts was 6:1 and the ratio of α, α-adducts to α,β-adducts was 4.4:1.
