Poly Vinyl Amide

N vinylacetamide nva is a non ionic monomer.

Poly vinyl amide.

It can be synthesized as a simple linear chain structure or cross linked typically using n n methylenebisacrylamide. Copolymer of nva and sodium acrylate called ge167 grade. Vinyl amide compare products.

For preparing poly piperazine amide composite membrane the pes ultrafiltration membrane was immersed for 3 min in aqueous solutions of pip 2 wt. Copolymers made of nva and other monomers can exhibit practical characteristics in addition to those common with the existing hydrophilic polymers. 352 59 k 半数致死量 ld 50 14 700 mg kg mouse 特記なき場合 データは常温 25 c 常圧 100 kpa におけるものである ポリビニルアルコール polyvinyl alcohol pva pvoh は合成樹脂の一種で 親水性が非常に強く 温水に可溶という特徴を持つ.

Poly n vinylacetamide pnva is a polymer having affinity for both water and alcohol made primarily from n vinylacetamide nva monomer. Polyacrylamide iupac poly 2 propenamide or poly 1 carbamoylethylene abbreviated as pam is a polymer ch2chconh2 formed from acrylamide subunits. The homopolymer of nva is called ge191 grade. The composite poly piperazine amide nanofiltration membrane was prepared by interfacial polymerization between piperazine pip with trimesoylchloride tmc.

In the cross linked form the possibility of the monomer being present is.
