- Abstract
Polyamide-6 /Polypropylene glycol (PPG) copolymers were synthesized via anionic polymerization of ε -caprolactam in the presence of inorganic additives - graphite and boron carbide using isophorone diisocyanate end functionalized PPG prepared in-situ as a macroactivator. Sodium caprolactam was used as an initiator. The influence of the graphite and boron carbide fillers on the degree of conversion was investigated. The copolymers obtained were characterized by 1H NMR and FTIR spectroscopies. The charpy impact strength of the composites was evaluated.
