Chain extender uye emulsifier yeaqueous polyurethane dispersions.Iyo aliphatic diamine sulfonic acid sodium munyu, inoshandiswa se hydrophilic chain extender kana hydrophilic monomer mukugadzirira kwemvura polyurethane resin, inokodzera majasi, ingi, anonamira uye matehwe ekupedzisa ejenti uye mamwe maindasitiri.Sodium ethylenediaminoethanesulfonate inogona zvakare kushandiswa mune mamwe minda se organic intermediates uye biochemical reagents.Yayo X-chinzvimbo uye yechipiri-chinzvimbo amino mapoka anogona kuita nemapoka e-isocyanate uye anowanzo kukurudzirwa kuti ashandiswe mune acetone process.Polyurethane dispersions akagadzirwa achishandisa AAS munyu ane yakanaka hydrolytic kugadzikana uye kuenderana kwakanaka nemamwe anionic kana nonionic aqueous dispersions.
