  • What is the molecular weight of Pam?
  • The molecular weight (MW) of commercial PAM ranges from 10 5 to >10 7 Da. High MW PAM (>10 6 Da) has a wider range of applications due to its high viscosity, drag reduction capabilities, and water retention characteristics. 6, 7, 8 PAM is widely used in environmental systems including: 1. 2. 3.
  • Is Pam thermally stable?
  • Thermal degradation PAM is generally thermally stable under normal environmental conditions, except at high temperatures within the range of 120–200 °C ( Çelik et al., 2018; Zhang et al., 2019 ).
  • Is Pam a low-risk chemical?
  • It also requires close collaboration among academia, government, and industry. Based on the findings of this study, it can be inferred that PAM is likely to be categorized as a low-risk chemical when employed as a soil amendment within acceptable dosage limits in farmlands.
  • Is Pam biodegradable?
  • Numerous studies have indicated the significant resistance of PAM to microbial degradation due to its substantial molecular weight, rendering it inaccessible to microbial attack ( Dai et al., 2014 ). Despite the low potential of PAM biodegradation, the process still exists in nature.
