Kodi 2,5-Furandione, dihydro-, monoisobutylene derivs CAS 67762-77-0 ndi chiyani?

(PIBSA, CAS 67762-77-0) ndi mankhwala ogwira ntchito omwe amapangidwa ndi momwe polyisobutylene yogwira ntchito kwambiri (Mn=1000) ndi maleic anhydride imagwirira ntchito. Ili ndi ntchito pamwamba, kufalikira komanso kukhazikika kwa kutentha, ndipo ndi gawo lofunikira pokonzekera zosakaniza zopanda phulusa, zosakaniza ndi zowonjezera mafuta. Magulu a polar ndi magawo osakhala polar mu kapangidwe kake ka molekyulu amapatsa mankhwalawa "amphiphilicity" yapadera.
