Abstract

Anion activated adiabatic polymerization of ε-caprolactam was investigated in the presence of various quantities of nano-SiO2. The parallel processes of crystallization and polymerization are separated first. Based on the crystallization kinetics and electron microscopic investigations it was shown that nano-SiO2 particles are heterogeneous nuclei for the crystallization of poly-ε-caprolactam. Further the time dependence of mean length of amorphous polymer macromolecules is determined experimentally.

Keywords: Adiabatic polymerization; crystallization; heterogeneous nucleation; average length of macromolecules
