Reactive compatibilization of polyamide-6 (PA 6)/polybutylene terephthalate (PBT) blends by a multifunctional epoxy resin

Reactive processing compatibilization of direct injection molded polyamide‐6/poly(ethylene terephthalate) blends

“…The crystallization temperature, during cooling, remained constant with the addition of PET, indicating that PET did not influence the crystallization of PA‐6. However, PBT promoted the crystallization of PA‐6 8. In agreement with previous works,20, 22 the crystallinity of PA‐6 (roughly 35%) remained practically constant in the blends of this study.…”

Preparation of core-shell structured particle and its application in toughening PA6/PBT blends

“…As seen, the melting peak around 214°C could be attributed to a small part of PA6, meanwhile, the melting peak around 221°C belonged to the overlapping peak of PA6 and PBT. Similar results were also observed previously by Chiou and Chang . And with the increase of PBMMA content, the two melting peaks gradually approached one another, presenting a broad melting peak after the modifier content was over 23.0 wt%.…”

“…(b), the curve of pure PA6/PBT blend exhibits two peaks: a big crystallization peak at higher temperature (192°C) and a small one at lower temperature (177°C). Because of the similar crystallization temperature of PA6 (181.9°C) and PBT (186.7°C), we could speculate that the small peak was formed by crystallization of a small part of PA6 and the big peak was the result of crystallization of both PA6 and PBT components. These two exotherms of the blends shifted to lower temperatures with the increase of PBMMA content and the small exotherm around 177°C disappeared at the modifier loading over 23.0 wt%.…”

Molecularly templated reaction for forming poly(dimethyl siloxane)–graphene oxide composite elastomers

“…Such a reaction forms stable CN chemical bonds without the evolution of by‐products, which gives rise to a macromolecular network structure and elastic properties (see Figure b‐d). It is noteworthy that similar reactions have been studied previously for synthesizing crosslinked nylons using multi‐functional epoxy crosslinkers, such as bisphenol‐A diglycidyl ether . One might suggest an alternative reaction mechanism involving carboxylic acids or hydroxyls on the surface of GO reacting with secondary amides.…”
