Abstract
Strong hydrogen bonding and the fast crystallization rate of polyamide 66 (PA66) bring difficulties in the fabrication of high-performance PA66 fibers. In this work, calcium chloride (CaCl2) was used as a modifier to regulate the crystallization rate and drawing performance of PA66. With the increased presence of CaCl2, the viscosity of PA66/CaCl2 increased, and the crystallization rate was significantly suppressed. At 5 wt % CaCl2, the crystallinity decreased from 31.36 to 19.52%, indicating a notable inhibition effect. The isothermal FTIR mechanism studies elucidated that a blueshift of the N-H stretching vibration can be observed, which resulted from the complexation between Ca2+ and the oxygen atoms on the amide groups disrupting the original hydrogen bond. The inhibition of hydrogen bonds promotes the fabrication of PA66 fiber with a draw ratio at 3.5 and a breaking strength at 5.16 cN/dtex. This work provides an effective way to enhance the spinnability and drawability of PA66 fibers.

Abstract
The characterization of polymer-polymer interfaces is of great interest to understand the diffusion process and chemical interactions in polymeric multiphase systems. This study investigated the formation of the interface layer between polyamide (PA) and polypropylene (PP) and its dependency on the maleic anhydride (MAH) content in PP. New insights with a very high level of details on the formation of the interfacial layer are obtained by employing a special technique of atomic force microscopy (AFM) combined with infrared (IR) for chemical imaging at nanoscale spatial resolution. This enables the determination of the interface thickness and even the observation and visualization of the diffusion gradient across the PA/PP interface layer. Combined with classical investigation methods such as interfacial energy and rheology, the method of nano-IR spectroscopy represents a very powerful tool to obtain more insights and a deeper understanding of the interfacial phenomenon in multiphase polymeric systems.
