Ngokusebenzisa i-polyfunctionality yama-carbohydrate, ukusabela kwe-acid catalyzed Fischer kwenziwa ukuze kukhiqizwe ingxube ye-oligomer lapho ngokwesilinganiso iyunithi ye-glycation engaphezu kweyodwa inamathiselwe ku-microsphere yotshwala. Isilinganiso senani lamayunithi e-glycose axhunywe eqenjini lotshwala lichazwa njengedigri (isilinganiso) se-polymerization (DPI. Umfanekiso2 ubonisa ukusatshalaliswa kwe-alkyl polyglycoside ene-DP=1.3. Kule ngxube, ukugcwala kwama-oligomers angawodwana) (i-mono- ,di-,tri-,-,glycoside) incike kakhulu kwisilinganiso seglucose notshwala kwinhlanganisela yokusabela(DP) iyisici esibalulekile ngokuphathelene nekhemikhali engokoqobo kanye nokusetshenziswa kwe-alkyl polyglycosides. Ekusabalaliseni okulinganayo, i-DP- yobude beketango le-alkyl elinikeziwe ihlobana kahle nezakhiwo zomkhiqizo eziyisisekelo, njenge-polarity, ukuncibilika, njll. Empeleni, lokhu kusatshalaliswa kwe-oligomer kungachazwa yi-PJFlory ngokuchaza ukusatshalaliswa kwe-oligomer kwemikhiqizo ngokusekelwe ama-polyfunctional monomers angasetshenziswa kuma-alkyl polyglucosides Le nguqulo eguquliwe yokusabalalisa i-Flory ichaza i-alkyl polyglycosides njengengxube yama-oligomers asabalaliswa ngokwezibalo.
Okuqukethwe kohlobo ngalunye kungxube ye-oligomer kuncipha ngezinga elikhulayo le-polymerization. Ukusatshalaliswa kwe-oligomer okutholwe yilo modeli wezibalo kuvumelana kahle nemiphumela yokuhlaziya (bona Isahluko 3). Ngamagama alula, i-avareji yedigri ye-polymerization(DP) yezingxube ze-alkyl polyglycoside ingabalwa kusukela kuphesenti lemvukuzane engu-pi yohlobo olufanele lwe-oligomeric oluthi “i” kungxube ye-glycoside (Umfanekiso 2)
Umfanekiso 2. Ukusatshalaliswa okujwayelekile kwama-oligomers e-dodecyl glycoside ku-DP
