Ultra-High Molecular Weights via Aqueous Reversible

This photomediated polymerization approach reaches number-average molecular weights in excess of 8.00 × 10 6 g/mol with degrees of polymerization above 85,000, making these, to our knowledge, the highest-molecular-weight polymers ever achieved via reversible-deactivation radical polymerization. In many cases, well-defined UHMW polymers can be

Mechanical degradation of polyacrylamide at ultra high

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 linear coordination polymers

Ultra-high molecular weight linear coordination polymers

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

US4617359A - High molecular weight polyacrylamide

This invention discloses a process for the polymerization of acrylamide and for the copolymerization of acrylamide with other monomers. It employs a ferrous/hydroperoxide redox initiator system that greatly enhances the molecular weight of the polymer formed. These high molecular weight acrylamide polymers offer outstanding advantages in enhanced oil recovery as injection water viscosifiers.
