  • Does polyacrylate main chain degrade in soil?
  • Results from the triple-labelled SAP were lower as compared to their single-labelled variant. Detailed results suggest that the polyacrylate main chain degraded in the soils, if at all, at rates of 0.12–0.24 % per 6 months. Superabsorbent polymers (SAP) are employed for a multitude of applications (Zohuriaan-Mehr and Kabiri 2008 ).
  • What are superabsorbent polymers (saps)?
  • Due to super high water absorption and water retention capacity, superabsorbent polymers (SAPs) can be applied to effectively ameliorate utilization of water in agriculture, such as retaining moisture in the soil and reducing the irrigation water consumption [ 2, 3 ].
  • Are polyacrylate-based SAPS biodegradable?
  • Nowadays, polyacrylate-based SAPs dominate the market. However they are non-biodegradable and most of them are thrown away in the nature or undergo incineration, either of which will impose a great damage to our environment.
  • Is polyacrylate a biodegradable polymer?
  • Taking polyacrylate-based SAP as an example, its polymer backbone consisting of fully carbon-carbon bonds make it non-biodegradable. The biodegradation rate decreases as molecular weight of non-cross-linked polyacrylates increases. This phenomenon is also frequently found in other polymers such as aliphatic polyesters.
