Hydroxyethyl acrylate
Bayanin Samfuri
Hydroxyethyl Acrylate (HEA) monomer ne mai aiki da yawa kuma babban tubalin gini ne a cikin sinadaran polymer. Yana da alaƙa mai haɗin acrylic mai polymerized da ƙungiyar hydroxyl mai amsawa a cikin ƙwayar halitta ɗaya. Wannan tsari yana ba shi damar yin copolymerization cikin sauƙi tare da nau'ikan monomers iri-iri yayin da kuma ke shiga cikin halayen haɗin gwiwa. Ruwa ne mai haske, mara launi zuwa rawaya mai haske kuma an san shi da haɓaka halayen aiki na samfuran polymeric na ƙarshe, koda lokacin da aka yi amfani da shi a ƙananan adadi.
