Ukuvumelana ne-Adipic Dihydrazide (ADH)

Inhlanganisela ye-Daam nge-ADH isetshenziswa kabanzi ezinhlelweni ezinhlelweni ze-polymer ezixhumene. Ukusabela phakathi kweqembu le-ketone le-daam neqembu le-hydrazide e-ADH kuphumela ekuxhumaneni okuhlala isikhathi eside kwe-hydrazone, ukunika amandla:

  • Amandla athuthukisiwe.
  • Ukumelana okuphezulu okuphezulu.
  • Ukuguquguquka okuhambisana nakho ngokuya ngezidingo zokwakheka.

I-Recreate Reaction Mechanism:

  1. Ukuxhumana kwe-Ketone-Hydrazide:Daam + adh → hydrazone bond
