Generally, poly(arylene ether) (PAEs) have been commercially produced using bisphenol-A (BPA) as petroleum-based aromatic monomer in the largest quantity. However, the use of BPA is limited to making plastics, because it behaves as an endocrine disruptor. The renewable monomer isosorbide (ISB) is one of the alternative candidates replacing BPA because of bio-based monomer having thermal-stability as well as high molecular rigidity. In this study, ISB based PAEs samples was successfully synthesized via nucleophilic aromatic substitution in solution polymerization with various type of difluoro aromatic monomers. The obtained PAEs were exhibited good thermal stability, mechanical properties and high molecular weight (Mw up to 100,000 g/mol) comparing to commercial BPA-based super engineering plastics. |
