論文題目:Malleable and Sustainable Poly(ester amide) Networks Synthesized via Melt Condensation Polymerization

摘要:Polymers synthesized directly from plant oils such as castor oil usually exhibit poor mechanical properties and cannot be reprocessed due to the soft, highly cross-linked and permanent cross-linking structures. Herein, we report a novel approach to synthesize high performance and malleable polymer networks, namely poly(ester amide) vitrimers, from castor oil via melt condensation polymerization with sebacic acid, polyamide 1010 monomer salt and 4-aminophenyl disulfide. 4-Aminophenyl disulfide with excellent thermal stability is applicable for high temperature polymerization and endows the poly(ester amide) network with malleability. Polyamide 1010 segments introduced by polyamide 1010 monomer salt endow the poly(ester amide) network with improved and tunable mechanical properties. This investigation demonstrates a new powerful strategy for developing high performance and reprocessable polymer networks from plant oils.
