N-vinyl-2-pyrrolidone → HCID 70233566, compound

Participants

Reaction Steps

The procedure in Example 1 was repeated except that 4.95 parts of N-vinyl-N-methylacetamide were used in place of N-vinyl-2-pyrrolidone to give a resin solution. The solid content of the resin solution measured by weight-loss on heating was 26.34% by weight. A broad peak at 2.7 ppm was confirmed by 1H-NMR [270 MHz, in (dimethylsulfoxide)-d6] and assigned to the N-methyl proton. From the ratio of integrated area for this methyl proton and that for the aromatic protons, it was confirmed that the resin was a copolymer constituted of p-hydroxystyrene unit and p-[1-(N-acetyl-N-methylamino)ethoxy]styrene in a ratio of 94:6. The resin was referred to as Resin R2.
