Kupyolera mu polyfunctionality yama carbohydrate, acid catalyzed Fischer reactions amapangidwa kuti apange osakaniza a oligomer momwe pafupifupi gawo limodzi la glycation limamangiriridwa ku microsphere ya mowa. Avereji ya mayunitsi a glycose olumikizidwa ku gulu la mowa amafotokozedwa ngati (average) degree of polymerization (DPI. Figure2 ikuwonetsa kugawa kwa alkyl polyglycoside ndi DP=1.3.) Mu kusakaniza uku, kuchuluka kwa oligomers payekha (mono- ,di-,tri-,-,glycoside) makamaka zimadalira chiŵerengero cha shuga ndi mowa muzomwe zimasakanikirana (DP) ndi khalidwe lofunika kwambiri la chemistry yakuthupi ndi ntchito za alkyl polyglycosides. Pakugawa kofanana, DP- ya kutalika kwa unyolo wa alkyl-imagwirizana bwino ndi zinthu zoyambira, monga polarity, solubility, ndi zina zotero. Ma polyfunctional monomers angagwiritsidwenso ntchito ku alkyl polyglucosides mtundu wosinthidwawu wa kugawa kwa Flory umafotokoza ma alkyl polyglycosides ngati chisakanizo cha oligomers ogawidwa.
Zomwe zili mumtundu wa oligomer zimachepa ndi kuchuluka kwa polymerization. Kugawa kwa oligomer komwe kumapezeka ndi masamuwa kumagwirizana bwino ndi zotsatira zowunikira (onani Mutu 3). M'mawu osavuta, kuchuluka kwa ma polymerization (DP) a alkyl polyglycoside osakaniza amatha kuwerengedwa kuchokera ku mole peresenti pi ya mitundu ya oligomeric "i" mu glycoside osakaniza (Chithunzi 2)
Chithunzi 2. Kugawa kofananira kwa oligomers ya dodecyl glycoside mu DP
