Isicelo

Imveliso ye-lactide evela kwi-lactic acid ekrwada isekelwe ikakhulu ekusetyenzisweni kwe-lactic acid condensation ukuvelisa i-oligomers ye-lactic acid, kwaye ii-oligomers ze-lactic acid zichithwa kwaye zihamba ngebhayisikile ukuvelisa i-lactide. Yonke inkqubo kufuneka iqhutywe phantsi kweemeko zokushisa okuphezulu, uxinzelelo olubi kunye ne-catalysis. Ngethuba lenkqubo, ukwenzela ukuba kuphuculwe isivuno esipheleleyo, i-inreactant kufuneka isetyenziswe kwakhona yi-reflux. Ekugqibeleni, iimveliso ze-lactide ezifanelekileyo zinokufumaneka ngeendlela ezithile zokucoca.
Njengemathiriyeli enokubola, isetyenziswa ikakhulu ukulungisa iipleyiti, iintsimbi zotyando, izinti zentliziyo, kunye nezigcwalisi zomzimba.
