Furthermore, procyanidins lowpolymer and procyanidins high polymer were separated by organic reagent extraction.

Plasticizer DOTP was prepared from ethylene glycol residue (major component is PET lowpolymer) using single step process in which alcoholysis and ester interchange were combined.
The composition analysis of procyanidins lowpolymer by HPLC showed that the compositions of the extracted product were the almost same as the compositions of standard procyanidins.
