Usoro mmepụta monomer
Mmepụta nke acrylamide monomer na-adabere na acrylonitrile dị ka akụrụngwa, n'okpuru ọrụ nke hydration nke na-akpali akpali na-emepụta ngwaahịa crude nke acrylamide monomer, mgbe flash distillation, a nụchara anụcha acrylamide monomer, monomer a bụ akụrụngwa maka mmepụta nke poly444 acrylamide.
Acrylonitrile + (mmiri ihe na-akpata / mmiri) → jikọtara → crude acrylamide → flash → nụchara anụcha → acrylamide a nụchara anụcha.
