Synthesis And Characterization Of Aromatic Substituted Polyactides PDF Download

The synthesis and characterization of new aromatic dichloride monomers containing benzoyl and phenylsulfonyl pendant groups and the corresponding polymers made via Ni(O)-catalyzed coupling polymerization are described. This work is an outgrowth of the previously described synthesis of poly(benzoyl-1,4-phenylene) from the Ni(O)-catalyzed coupling polymerization of 2,5-dichlorobenzophenone. The new monomers containing benzoyl pendant groups were synthesized by the Friedel-Crafts reaction of 2,5-dichlorobenzoyl chloride and substituted benzenes to give structures that were substituted at the para position on the pendant benzene ring. The substituents include fluorine, methyl, ethyl, and isopropyl.
