Los ntawm polyfunctionality ntawm carbohydrates, acid catalyzed Fischer cov tshuaj tiv thaiv yog conditioned los tsim ib tug oligomer sib tov nyob rau hauv uas nyob rau hauv nruab nrab ntau tshaj ib tug glycation unit yog txuas mus rau ib tug cawv microsphere. Qhov nruab nrab tus naj npawb ntawm glycose units txuas mus rau ib pawg cawv yog piav raws li (nruab nrab) degree ntawm polymerization (DPI. Daim duab 2 qhia txog kev faib rau alkyl polyglycoside nrog DP = 1.3. Nyob rau hauv qhov sib tov no, qhov concentration ntawm tus neeg oligomers (mono- ,di-,tri-,-,glycoside) feem ntau yog nyob ntawm qhov sib piv ntawm cov piam thaj rau cawv hauv cov tshuaj tiv thaiv sib tov Qhov nruab nrab ntawm polymerization (DP) yog ib qho tseem ceeb ntawm kev hais txog lub cev chemistry thiab kev siv ntawm alkyl polyglycosides. Nyob rau hauv ib qho kev sib npaug, DP- rau ib qho alkyl saw ntev-correlates zoo nrog cov khoom siv yooj yim, xws li polarity, solubility, thiab lwm yam. Nyob rau hauv txoj cai, qhov kev faib oligomer no tuaj yeem piav qhia los ntawm PJFlory rau piav qhia txog oligomer tis ntawm cov khoom raws li. polyfunctional monomers kuj tuaj yeem siv rau alkyl polyglucosides Qhov hloov kho no ntawm Flory faib piav qhia txog alkyl polyglycosides raws li kev sib xyaw ntawm statistically faib oligomers.
Cov ntsiab lus ntawm ib tug neeg nyob rau hauv oligomer sib tov txo nrog nce qib ntawm polymerization. Lub oligomer faib tau los ntawm tus qauv lej no ua tau zoo nrog cov txiaj ntsig kev ntsuas (saib Tshooj 3). Hauv cov ntsiab lus yooj yim, qhov nruab nrab qib ntawm polymerization (DP) ntawm alkyl polyglycoside sib tov tuaj yeem xam los ntawm mole feem pua pi ntawm cov hom oligomeric "i" hauv cov sib xyaw glycoside (Daim duab 2)
