A novel schiff base (BD) containing nitrogen and silicone was prepared, a phosphorus–nitrogen flame retardant (BDD) synthesized based on BD 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO). It found that the structure of changed continuously during heating process formed self-cross-linking network at about 400 °C, while porous fluffy shape by BDD as an intumescent retardant. The char yields 700 °C were 62% 38% in nitrogen, respectively. obtained blended to enhance retardancy...
A facile melt polymerization method for polyamide-6 based thermoplastic elastomers with a well-defined microphase separation structure is proposed.
The melt polymerization of polyamide 6 (PA6)-based thermoplastic elastomers with high-content and high-molecular-weight soft segments (HS-TPAEs) has posed a long-standing challenge, rendering them unsuitable for filament presentation in textiles.
A facile route was provided to prepare silicon/nitrogen synergistically reinforced flame-retardant PA6 nanocomposites with simultaneously improved anti-dripping and mechanical properties.
Abstract To illustrate the complex phase evolution of polyamide 6 (PA6)‐based thermoplastic elastomer (TPAE‐50) with a three‐phase system (a pure PA6 crystalline phase, phase‐separated mesophase, and mixed phase) during cooling heating, in situ IR spectroscopy combined moving‐window 2D correlation analysis is employed. The mixing amorphous domains soft melting imperfect TPAE‐50 occur from 60 °C increasing temperature. Brill transition happens to heating at 140–160 170–135 °C, respectively....
Abstract A novel micro cross‐linking technology is proposed to enhance the mechanical properties of poly(ethylene terephthalate) (PET)‐based thermoplasctic elastomers (TPEEs) whose molecular weights are difficultly increased via traditional synthetic technologies. It found that brittle fractures TPEEs, usually observed in polymers with low weights, can be converted into ductile form introduction a certain fraction 1,2,3,4‐butane tetracarboxylic acid as agent. Unlike technologies, which cause...
Unusual nonlinear rheological phenomenology in uniaxial extension of polystyrene solutions and melts.
Abstract The facile characterization of isothermal microphase separation kinetics in polyamide 6 (PA6)‐based thermoplastic elastomers (TPAE‐6) has long posed a challenge for the development suitable melt spinning processes. In this study, is addressed through differential scanning calorimetry (DSC) measurements. It assumed that enthalpy changes TPAE‐6 during process are linear superposition associated with and crystallization PA6 hard phases, resembling without soft segments (TPAE‐6‐0)....
In this work, we apply lubricated squeezing to perform planar extension of styrene-butadiene rubbers (SBRs) and illustrate how large step-strained SBR undergo chain relaxation. When the imposed step strain is moderate or stepwise sufficiently slowly, stress relaxation spatially uniform. Upon a over period much shorter than overall time, strained inhomogeneous molecular relaxation, plausibly due localized disentanglement that results from force imbalance. As manifestation elastic yielding,...
