Iithegi zeMveliso

Yintoni i-2,5-Furandione, i-dihydro-, i-monopolyisobutylene derivs CAS 67762-77-0?

(PIBSA, CAS 67762-77-0) yikhemikhali esebenzayo eyenziwe ngokusabela kwe-polyisobutylene esebenzayo kakhulu (Mn = 1000) kunye ne-anhydride ye-maleic. Inomsebenzi womphezulu, i-dispersibility kunye nokuzinza kwe-thermal, kwaye ingundoqo ephakathi ukulungiselela i-ashless dispersants, i-emulsifiers kunye ne-lubricant additives. Amaqela e-polar kunye namacandelo angekho kwi-polar kwisakhiwo sayo se-molecular inika imveliso "i-amphiphilicity" ekhethekileyo.
