Synthesis and chemoselective crosslinking of functionalized polyesters from bio?based epoxides and cyclic anhydrides

Biomass derivable epichlorohydrin undergoes ring-opening copolymerization with either succinic or itaconic anhydride (both biosourcable) under standard laboratory conditions using metal-based an entirely organic initiator to form highly functionalized, low molecular weight polyesters. The linear polyesters obtained from and contain both alkyl chlorides ?,?-unsaturated esters can be crosslinked insoluble resins by treatment di- tetra-functional amines thiols. Crosslinking predominately occurs through the whilst crosslinking thiols allowing synthesis of polyester derived complementary controllable functionalities.
