| Abstract: | Composites of nylon 6 and thermoplastic polyester-based urethane elastomer(MCPA6/PUR-T) were synthesized with ε-caprolactam via in-situ anionic ring-opening polymerization.When compouding with 1.1% PUR-T,the breaking enlongation of the composite was greatly increased and reached 214.5%(which was 247% higher than that of the pure MCPA6).Moreover,the notched izod impact strength of the composite was also enhanced with the increase of the PUR-T content.Ductile fracture was found during the SEM characterization process,and only α-form crystal of nylon 6 existed in the composite detected by wide-angle X-ray diffraction.Furthermore,the crystallization temperature and glass-transition temperature were decreased with increasing PUR-T content,which indicated that the interaction between polyamide 6 chains was weakened by PUR-T. |
