Two hindered phenol antioxidants, HPAP-COOH and HPAP-HA for polyamide, were synthesized by bonding aromatic carboxylic acids amides to phenols. The antioxidant effect of the two antioxidants in PA6 was studied thermal oxidative aging. results showed that had good effects, especially HPAP-COOH. PA6/HPAP-COOH exhibited excellent retention tensile strength bending after aging, slightly higher than PA6/1098. not only has a but also plasticizing PA6. elongation at break unaged PA6/HPAP-HA 3.7 8.3...
Poly(3,4-ethylenedioxythiophene) (PEDOT) is a prospective thermoelectric polymer owing to high conductivity, low thermal and processability. However, the Seebeck coefficient of PEDOT substantially lower than inorganics, molecular design strategies promote this are yet be established. Here, introduction chloromethyl (-MeCl) on surface has been established as an effective strategy for elevating its coefficient. It was found that electron-withdrawing effect -MeCl decreases highest occupied...
It was found that bases may modulate doping levels by removing proton and improve carrier mobility of PEDOT:PSS.
Poly (styrene-maleic anhydride) copolymers, due to their unique structure, are extensively functionalized and modified for preparing heat stabilizers, compatibilizers, other functional additives. Using 4-methylpent-1-ene-2,4-diyl diphenyl (α-MSD) as a chain transfer agent, series of molecular-weight-controlled maleic anhydride-derived styrene poly(N-p-fluorophenylmaleimide-alt-styrene) (PFS) poly(N-p-carboxylphenylmaleimide-alt-styrene) (PCS), were synthesized via free radical...
The effect of electron donor groups on oxidation resistance was studied, and then the mechanism thermal oxygen aging PA6 studied.
Phosphogypsum is a solid waste with great environmental stockpile pressure produced by the wet production of phosphoric acid. Although there are various methods to purify and utilize phosphogypsum, means for environmentally friendly, low energy consumption, high value-added utilization still need be further explored. Here, CaSO
In order to expand its application range in electronics and membrane industries, this paper aimed develop polyamide 6 (PA6)/P (N-(4-carboxyphenyl) maleimide-alt-triallyl isocyanurate) (PCT) composites with heat-resisting, thermally conductive anti-moisture, by employing PCT as a reactive reinforcement material applying irradiation for solid-state interfacial reaction (SSIR) between PA6. According the results, SSIR occurred PA6 PCT. Compared non-SSIR PA6, PA6/PCT composite showed highest heat...
ABSTRACT P(N‐phenylmaleimide‐alt‐styrene) (PNS) was synthesized, and nylon 6 (PA6)/PNS blends were prepared by melt blending. The heat resistant crystallographic properties of PA6/PNS with different contents investigated analyzed. results showed that the deflection temperature ( HDT ), relative crystallinity X n dynamic viscosity η ) increased increasing PNS. differential scanning calorimetry proved PNS had played a positive role in nucleating PA6. Scanning electron microscosopy domains...
P(N-phenylmaleimide-alt-styrene) (P(NPMI-alt-St)) and P(N-(4-carboxyphenyl)maleimide-alt-styrene) (P(CPMI-alt-St)) were designed synthesized via free radical copolymerization. Fourier transform infrared spectroscopy (FT-IR), nuclear magnetic resonance (¹H NMR 13C NMR), gel permeation chromatography (GPC), differential scanning calorimetry (DSC) used to confirm the structure of P(NPMI-alt-St) P(CPMI-alt-St). Next, effect P(CPMI-alt-St) on heat deflection temperature (HDT) nylon 6 was studied....
Poly (lactic acid) (PLA) is a promising biodegradable plastic, but its flammability limits application. In this work, phenylmaleimide bridged phosphaphenanthrene derivatives (DHD) containing bisphosphaphenanthrene and groups was synthesized flame retardant PLA composites were prepared. The results showed that DHD endowed superior performance in PLA. With the addition of just 2.5 wt% DHD, composite has limiting oxygen index (LOI) 28.6% achieved UL-94 V-0 rating. Meanwhile, peak heat release...
In this work, nylon 6/ P(N-phenylmaleimide-alt-styrene) blends were prepared by melt blending, and the mechanical, heat-resistant, crystallographic dynamical mechanical properties of with different contents investigated analyzed. The results showed that decreased increasing PNS, while heat deflection temperature (HDT), relative crystallinity (Xn), storage modulus (G’) increased PNS. differential Scanning Calorimetry (DSC) proved PNS played positive role nucleating PA6. And dynamic...
Abstract The investigation of the polymerization kinetics and thermal degradation maleic anhydride copolymers is significant reference value for synthesis multifunctional high-performance anhydride-based their applications in different fields.

The development of alternative refrigerants with low global warming potentials (GWP) has become a trend in response to the increasing demands for environment protection. R1234ze(E) and R290 have extremely GWP values are potential substitutes. However, their flammability limits applications under high-temperature conditions. In this study, R134a was experimentally investigated its flame-retardant effect on at 60°C. ranges pure flammable were measured, variations binary mixtures, namely,...
