Homo‐ and copolymers of furan–maleic anhydride and furan–dimethylacetylene dicarboxylate adducts via aqueous ring‐opening metathesis polymerization

Abstract
Homo‐ and copolymers of the Diels‐Alder adduct of furan with maleic anhydride (F‐MA) and of furan with dimethylacetylene dicarboxylate (F‐DMAD) were synthesized by aqueous ring‐opening metathesis polymerization and characterized by IR, NMR, and DSC. Microstructural product analyses by 13C‐NMR indicated the copolymer composition to be 50 : 50 of each of the monomers when an equimolar mixture of RuCl3 and K2RuCl5, was used as the catalyst, with the cis‐form predominant for poly(F‐MA) and the trans‐form predominant for poly(F‐DMAD). On the practical side, the acidic and ester functionality of the copolymer would lend itself to be both blendable (and selectively extractable) with some already existing petroleum‐based acrylate polymers. © 1993 John Wiley & Sons, Inc.
