Hydrogenative Depolymerization of Nylons [PDF]

Journal of the American Chemical Society, 2020
The widespread crisis of plastic pollution demands discovery of new and sustainable approaches to degrade robust plastics such as nylons. Using a green and sustainable approach based on hydrogenation, in the presence of a ruthenium pincer catalyst at 150 °C and 70 bar H2, we report here the first example of hydrogenative depolymerization of ...

Copolyamides of nylon‐4,6 and nylon‐4,T [PDF]

Journal of Polymer Science Part A: Polymer Chemistry, 1989
AbstractCopolyamides of nylon‐4,6 and nylon‐4,T were prepared by a two‐step method: (1) a prepolymerization in an autoclave (40 min at 210°C) and (2) a postcondensation in the solid state (4 h, 260°C). On these materials was studied the melting behavior with DSC, the crystalline structure with WAXS, the water absorption, and the mechanical properties ...
