Homo- and Copolymers of N-Acryloylpyrrolidine and N-Vinylpyrrolidone as Kinetic Inhibitors of Hydrate Formation

Two copolymers of N-acryloylpyrrolidine and N-vinylpyrrolidone with a different ratio of monomeric units and two homopolymers; poly-N-acryloylpyrrolidine and poly-N-vinylpyrrolidone, were synthesized to study the effect of the composition of macromolecular compounds (MMC) on their inhibiting power d...

Beschreibung
Zusammenfassung:	Two copolymers of N-acryloylpyrrolidine and N-vinylpyrrolidone with a different ratio of monomeric units and two homopolymers; poly-N-acryloylpyrrolidine and poly-N-vinylpyrrolidone, were synthesized to study the effect of the composition of macromolecular compounds (MMC) on their inhibiting power during formation of gas hydrates. The composition of the MMC was confirmed by ¹H and ¹³C NMR spectroscopy and the ratio of monomeric units in the copolymers was determined with the ¹H NMR spectra. The inhibiting power of the synthesized MMC was determined during hydrate formation.
