Cyclosiloxane-containing polymers and the formation of highly stable elastomer

Cyclotetrasiloxane-containing polymers are a special kind of macromolecule, but currently there is a lack of efficient ways to prepare suitable monomers. Herein, we would like to report the synthesis of a series of cyclotetrasiloxanes with two SiH groups, which are then used for preparation of various ring-containing polymers. The resulting polymers can be cured with simple organic bases to obtain transparent elastomers which leave no metal leftover and are highly thermally stable.
