basic information
[Lecture 1] Blending of different types of polymers is an important means to improve polymer performance. However, since different types of polymers generally do not mix well, sufficient improvement effects are often not achieved. Therefore, it is important to devise mixing and dispersion methods to control the structure of polymer blends and enhance their performance. This lecture will outline the influence of mixing conditions on the structure of polymer blends. It will also discuss structural control techniques through reactive processing, known as reactive alloying. Furthermore, methods for controlling various physical properties through structural control of polymer blends will be described. [Lecture Abstract] The PK/PA polymer alloy, which is thought to consist of a co-continuous structure rich in polyketone (PK) and polyamide 6 (PA) and an inverse sea-island structure, exhibited impact resistance far exceeding that of PC when moisture was absorbed. Using techniques such as TEM, 3D-TEM, Raman and IR spectroscopy, SAXS, solid-state high-resolution NMR, and viscoelasticity, the lecture will clarify that the improvement in impact resistance is due to the reinforcement effect of the lamellar network, which retains maximum stress, as well as the significant elongation arising from the increased mobility of the moisture-absorbed PA dispersed phase and the interactions between the PA and PK-rich phases.
