polyacrylamide for edge-water encroachment suppliers in saudi arabia
The change in polyacrylamide size distribution was evaluated by size exclusion chromatography. The peak polymer molecular weight (MW) after a single-pass through the capillary decreased from 10[superscript 7] to 7 × 10[superscript 5] Da at deformation rate V/R = 4 × 10[superscript 6] s[superscript −1].
Ultra-high molecular weight (UHMW, M n > 1000 kDa) polymeric drift control adjuvants (DCAs) for agricultural spraying are prone to mechanical degradation and rapidly lose performance. To overcome this, we have designed linear coordination polymers (LCPs) composed of 400 kDa telechelic bis-terpyridine end-functionalised polyacrylamide units, which ‘self-heal’ upon shearing through
