Tezisda atsetillangan bug'doy kepagi arabinoksilani (DS ≈ 1,5) asosidagi plyonkalarning termik xossalariga plastifikator tabiatining ta'siri nazariy tahlil qilingan. Glitserin, trietilsitrat va polietilenglikol-400 polyarlik, molekulyar massa, uchuvchanlik va polimer bilan moslik bo'yicha solishtirilgan; erkin hajm nazariyasi va Foks tenglamasi asosida 20 % plastifikator ulushida shishalanish haroratining (Tg) kutilayotgan pasayishi baholangan. DSC va TGA bo'yicha kutilayotgan qonuniyatlar umumlashtirilib, uch plastifikatorni bir xil ulushda solishtiruvchi tajriba rejasi va baholash mezonlari asoslangan.
