Copolymers of epichlorohydrin (ECH) and 1,2‐epoxyhexane (EpH) have been synthesized via cationic ring‐opening polymerization using BF3×THF as a catalyst. Structures of the resulting polymers have been confirmed by IR and NMR spectroscopy and GPC. In a subsequent reaction with NaN3 in DMSO, the halogenated precursors were completely azidated, which was confirmed by the same spectroscopic methods. The...
Plasticization of PVC was carried out by covalently linking phthalate derivatives via copper-free (thermal) or copper catalyzed azide-alkyne cycloadditions. Di(2-ethylhexyl) phthalate derivatives (DEHP-ether and DEHP-ester) were synthesized and appended to PVC at two different densities. The glass transition temperatures of the modified PVC decreased with increasing content of plasticizer. PVC-DEHP-ether...
