Copolyamides of nylon‐4,6 and nylon‐4,T [PDF]
Journal of Polymer Science Part A: Polymer Chemistry, 1989 AbstractCopolyamides of nylon‐4,6 and nylon‐4,T were prepared by a two‐step method: (1) a prepolymerization in an autoclave (40 min at 210°C) and (2) a postcondensation in the solid state (4 h, 260°C). On these materials was studied the melting behavior with DSC, the crystalline structure with WAXS, the water absorption, and the mechanical properties ...

Gradient all-nanostructured aerogel fibers for enhanced thermal insulation and mechanical properties [PDF]
Nature CommunicationsLightweight, nanoporous aerogel fibers are crucial for personal thermal management and specialized heat protection. However, wet-spinning methods, exemplified by aramid aerogels, inevitably form a dense outer layer, significantly reducing the volume ...

Preparation and some properties of nylon-4,2 [PDF]
, 1984 An attempt was made to produce a new short-chain alphatic polyamide nylon-4,2. This polyoxamide can be prepared by polycondensation of tetramethylene diamine and diethyl oxalate.
