Vinylpyrrolidone / Vinyl Acetate
VP / VA Copolymers waxay leeyihiin cunno kala duwan oo ah vinylpyrrolidone ilaa vinyl acetate waxaana loo heli karaa budo cad ama xalal hufan oo biyo, ethanol iyo isopropanol. iyo biraha, guryahaani, oo ay weheliso awooda lagu xakameynayo nafaqeyntooda biyo-mareenka iyada oo loo marayo qaab-dhismeedka monomer, waxay horseed u tahay dalab ballaaran oo warshadeed.
