Foma'i vasega PLGA (Poly DL-lactide-co-glycolide)CAS26780-50-7 fale gaosi polymers ma sili ona lelei

O le PLGA o le copolymerization fa'afuase'i, polymer amorphous, fa'aaoga lautele i suture ta'otoga, fa'aputu-adhesion membrane, fa'ainisinia fa'ameamea.Pe a faatusatusa i le PLA, o le polymer degradation taimi e mafai ona pulea e tusa ai ma le anotusi Ga eseese, ma o le mea e vaivai ma elastic.O ituaiga eseese o le PLGA e mafai ona saunia i fua eseese o monomer.Mo se faʻataʻitaʻiga, PLGA 75:25 o loʻo faʻaalia ai o le polymer e aofia ai le 75% lactic acid ma le 25% glycolic acid.O le tikeri faʻaleagaina o le PLGA e ese mai le fua faʻatatau o le monomer, ma o le maualuga o le vaega o le ethyl lactide, o le faigofie foi lea ona faʻaleagaina.
