Effects of mixing time and blend composition on properties and morphologies of polyamide 6/polycarbonate blends

Summary

The role of the mixing time and the composition of polyamide 6/polycarbonate, PA6/PC, mixtures was investigated by torque and thermal measurements as well as by Molau test and morphological analysis.

PA6 and PC are clearly incompatible over the whole range of composition showing well segregated phases. However, at high PA6 content and long time of mixing no more phase separation is observed. This has been attributed to chemical reactions between PA6 and PC molecules, that give rise to some block copolymers, which act as interfacial agents between the two polymers.

The copolymer extracted from 75/25 PA6/PC blend, mixed for 45 min., shows Tg at about 65°C and two endotherm peaks at 127 and 211°C.
