Abstract

This paper presents the fractionation of PA-6 obtained at temperature below its melting point. Unfractionated samples and polymer fractions were studied by viscosimetry, thermogravimetry (TG, DTG) and differential scanning calorimetry (DTA). It was shown that at the first step of synthesis the polymer is formed with a predominantly linear structure and high parameters of thermal properties. At the second synthesis step the molecular weight of the polymer and its thermal properties increase and subsequent demonomerization-drying is accompanied by a further increase in the polyamide molecular weight.
