Abstract
The synthesis of poly(methyhydrosiloxane) (PMHS) and N,N'-bis(3-allyl)pyromellitic diimide was optimized for O2/N2 separation. The membrane exhibits excellent mechanical and thermal properties and shows an O2/N2 selectivity of up to 4.44 with an O2 permeability of 31.0 Barrer; compared with polydimethylsiloxane (PDMS) and pure polyimide (PI) membranes, the separation selectivity shows a 107% increase for PDMS, and the permeation shows a 660% increase for pure PI. The obtained results were well above the ones reported on the literature for similar conditions opening the door for the preparation of a stable polysiloxane (PMHS-I) gas separation membrane with extraordinary O2/N2 separation performance.

Abstract
Benzocyclobutene (BCB), as a reactive group, was incorporated into the side chains of polysiloxane via platinum/carbon hydrosilylation reaction. The hydrosilylation reaction showed good tunability for the incorporation ratio of BCB pendant groups. Differential scanning calorimetry results revealed that upon heating the BCB-containing polysiloxanes, great exothermic reaction occurred via [4+2] cycloaddtion reaction involving vinyl and BCB. The onset decomposition temperature ( Tdonset) of the BCB-siloxane resins reaches 518°C. This high Td demonstrates an excellent thermal resistance. The high-temperature performance of the resulting polymers illustrates the power of benzocyclobutene pendant groups in the design and preparation of potential high-performance silicon resins.
