What is nonionic polyacrylamide?

Nonionic polyacrylamide is homopolymer formed of acrylamide, with high purity, good soEubility. high molecular weight. This series of products are with high molecular weight polymer and liner polymer low ion degree.

Can nonionic polyacrylamide be used as a gel fracturing fluid?

Nonionic polyacrylamide (NPAM) with controlled molecular weight was successfully synthesized as a gel fracturing fluid by aqueous solution polymerization.

How to control NPAM molecular weight?

The NPAM molecular weight can be controlled by adjusting these factors. The decisive factor is the acrylamide concentration, whereas the initiator concentration and feeding temperature are secondary factors. These synthetic NPAMs can be crosslinked with zirconium acetate to produce a gel fracturing fluid for use in low permeability oil reservoirs.
