摘要：
New phenyl substituted siloxyl diacetylene polymers have been prepared in high yields. The syntheses are one-pot, two step procedures involving the reaction of dilithiobutadiyne with various dichlorodisiloxanes. Spectroscopic and microanalytical data support the proposed structures. The polymers are thermally crosslinked to give hard, void-free thermosets which can be further heated to give ceramic products with high weight retention.
