Ma o ka polyfunctionality o nā carbohydrates, acid catalyzed Fischer reactions is conditioned to produce a oligomer mixture in which on average oi aku glycation units attached to a alcohol microsphere. Ua wehewehe ʻia ka helu awelika o nā ʻāpana glycose i hoʻopili ʻia i kahi pūʻulu waiʻona e like me ke degere (awelika) o ka polymerization (DPI. Hōʻike ka Figure2 i ka puʻunaue ʻana no kahi polyglycoside alkyl me DP=1.3. I loko o kēia hui ʻana, ke ʻano o nā oligomers pākahi (mono- ,di-,tri-,-,glycoside) pili nui i ka ratio o ka glucose i ka waiʻona i loko o ka hui hoʻoheheʻe ʻana ʻO ka degere awelika o ka polymerization(DP) he ʻano koʻikoʻi e pili ana i ke kemika kino a me ka hoʻohana ʻana i nā polyglycosides alkyl. Ma ka mahele kaulike, ua pili pono ka DP- no ke kaulahao alkyl i haawiia me na waiwai huahana kumu, e like me ka polarity, solubility, etc. Ma ke ano nui, hiki ke wehewehe ia keia mahele oligomer e PJFlory no ka wehewehe ana i ka mahele oligomer o na huahana e pili ana. Hiki ke hoʻopili ʻia nā monomers polyfunctional i nā polyglucosides alkyl i wehewehe ʻia kēia mana hoʻololi o ka puʻunaue Flory i nā polyglycosides alkyl ma ke ʻano he hui ʻana o nā oligomers i puʻunaue ʻia.
Ke emi nei ka ʻike o kēlā me kēia ʻano i ka hui oligomer me ka piʻi ʻana o ka polymerization. ʻO ka puʻunaue oligomer i loaʻa mai i kēia kumu hoʻohālike makemakika, ua kūpono loa me nā hualoaʻa analytical (e nānā i ka Mokuna 3). Ma nā ʻōlelo maʻalahi, hiki ke helu ʻia ke degere awelika o ka polymerization(DP) o nā huila polyglycoside alkyl mai ka mole pakeneka pi o kēlā me kēia ʻano oligomeric "i" i loko o ka hui glycoside (Figure 2)
