  • Can ultra-high molecular weight polymers have a low dispersity?
  • In the forefront of advanced materials, ultra-high molecular weight (UHMW) polymers, renowned for their outstanding mechanical properties, have found extensive applications across various domains. However, their production has encountered a significant challenge: the attainment of UHMW polymers with a low dispersity (Ɖ).
  • What is a high mw polyacrylamide (PAM) well?
  • During HVHF operations, fluids containing ultrahigh MW polyacrylamide (PAM) (2 × 107 Da) are pumped at high flow rates down through the wellbore and into tight shale formations, creating highly permeable fractures under high hydraulic pressure (up to 10000 psi ( ref. 4 )).
  • What is ultra-high molecular weight (UHMW) polymer used for?
  • Ultra-high molecular weight (UHMW) polymers have found applications in various fields ranging from medical implants, industrial products such as conveyor belts, gears, bearings, etc., in the aerospace industry as parts of engine, wing components and landing gears, in sports equipment to even bulletproof vests 1.
  • Does a non-chemical pathway-mechanical degradation of polyacrylamide exist during HVHF?
  • This study focused on a non-chemical pathway-mechanical degradation of polyacrylamide under ultra-high fluid strain conditions (∼10 7 s −1) that uniquely exist during HVHF but has not yet been explored experimentally.
