In Situ Synthesis of Chemically Stable Hybrid Co-Networks of Poly(thioctic Acid) with Fe via Controlled/Living Cationic Ring-Opening Polymerization.

The novel chemically stable hybrid co-networks (PTA-Fe) of poly(thioctic acid) coordinated with molar content (C) of 1%∼12% Fe generated from [FeCl·POH] can be in situ synthesized via controlled/living cationic ring-opening polymerization of α-thioctic acid (TA) with tert-butyl chloride(BCl)/FeCl/isopropanol(POH) initiating system at 0 °C. The polymerizations are all in first order with respect to monomer, initiator and co-initiator. The resulting PTAs with desired molecular weights and relatively narrow unimodal molecular weight distribution can be obtained via quantitative initiation by changing [BCl].
