A Plastic That Behaves Like Glass

Malleable material contains esters that swap positions in cross-links when the polymer is heated
Department: Science & Technology
Keywords: thermoset plastics, polymers, polyester, transesterification

Chemists in France unveiled this year a material that mimics the malleability of glass but retains the toughness and stability of thermoset plastics (C&EN, Nov. 21, page 5; Science, DOI: 10.1126/science.1212648). The polymer could be useful to make parts for the automotive and aerospace industries, among others. “Anywhere you have a complex shape, you can use this material,” said lead . . .
