Abstract
In this article the alcoholysis process conditions of secondary polyethylene terephthalate with the mixture of polyatomic
alcohols have been investigated.This study has found that the aggregative state of the alcoholysisproducts of secondary
polyethylene terephthalate with glycerineis solid, and does not meet the requirements of the technological indicator of
polyurethane foam. The structure of the resulting hydroxyl-containing polyesterpolyols was studied by IR-spectroscopy.
The influence of the physical-chemical properties of alcoholysis products on the molar ratio of SPET with glycerine and
the duration of the reaction has been shown. The structure and technological properties of the products obtained have
been determined. There have been achieved to obtain fluid hydroxyl-containing polyesterpolyols with adjusted viscosity
on the basis of polyatomic alcohols through alcoholysis.

Key words: secondary polyethylene terephthalate, glycerine, diethyleneglycol, alcoholysis, physical-chemical properties, structure.
