Fig. 1From: Triphenylphosphine-based functional porous polymer as an efficient heterogeneous catalyst for the synthesis of cyclic carbonates from CO2 TG curves of (a) TPDB, (b) TPDB-BP, and (c) TPDB-BP-TEA. TPDB was found to be stable up to 300 °C as evidenced by TG (curve a). After the modification with BP and TEA, the thermos stability of the obtained samples TPDB-BP and TPDB-BP-TEA slightly decreased to 250 °CBack to article page
