Elastomer is one of the important materials for vibration and noise reduction.However, its narrow effective damping temperature range (tanδ ≥ 0.3) remains to be a major issue that hinders its application as a damping material. Herein, we precisely design and synthesize a polyurethane structure where specific dangling chains with both electron-donating group and electron-absorbing group were introduced into prepolymers, generating more hydrogen bonding interaction with the main chain to hinder microphase separation. At the same time, hyperbranched polyester as a cross-linking agent increases its free volume effectively. The synergy effect of enhancement of hydrogen bonding, decrease of microphase separation, and increase of free volume results in a higher damping polyurethane elastomer with a great wider effective damping temperature range up to 175°C (−60°C-115°C), which provides a new idea for the preparation of damping elastomer.

The structure and the physical properties of several polyamide 66 (PA66)/polyamide 12 (PA12) blends containing different amounts of the two polymers and obtained by melt‐blending have been investigated. A low amount of organically‐modified layered silicate (OMLS, 4 wt%) has also been introduced in order to further improve the physical properties and, in particular, to evaluate its effect on the blends' structure and components' miscibility. The microstructure and morphology of all the composites were analyzed by means of X‐Ray diffraction (WAXD), transmission electron microscopy (TEM), and high resolution scanning electron microscopy (SEM), while the macroscopic scale properties (mechanical behavior and water adsorption) were assessed in order to investigate and understand the materials' structure–properties relationships. The partial miscibility of PA66 and PA12, with phase separation depending on blend composition, has been confirmed. The results also underlined the possibility to tailor the behavior of polymer blends in terms of mechanical water adsorption properties by varying the amount of PA12, added to PA66 with and without the addition of the OLMS. The effectiveness of the clay in modifying the components' miscibility as well as its tendency to segregate preferentially within separate PA66 domains have been assessed. WAXD results showed opposite effects of PA12 and clay on the crystallization behavior of PA66, an aspect that has also been deepened in another paper by the same authors discussing the results of the complete thermal characterization.
