The kinetics of the reactive blending process occurring during the stirred melting of polyamide 6/polycarbonate (PA6/PC), polyamide 6/polycarbonate/poly(propylene oxide) (PA6/PC/PPO) in a Haake internal mixer at 240°C were investigated. In the PA6/PC blends the formation of copolymers can be observed and they act as compatibilizing agents, raising the miscibility of these blends. In the PA6/PC/PPO blends, the composition is very important in creating the PA6-PC copolymers. The rise of the PPO percentage increases the mobility of the PA6 molecules and the probability of formation of PA6-PC copolymers in PA6/PC/PPO blends with 10% w/w of PC. The PPO percentage (3-10 phr) influences the kinetics of reaction of PA6/PC/PPO ternary blends with a constant PA6/PC mass ratio (85/15). |
