18. Fibrillar and microfibrillar structures in poly(p-phenylene terephthalamide) fibers
The microfibrils and the microfibrillar network in poly(p-phenylene terephthalamide) (PPTA) fibers formed during the coagulation from a monodomain lyotropic fiber are stabilized by critical point drying and characterized by electron microscopy and small angle X-ray scattering. The diameter of the microfibrils varies from 20 to 49 nm depending on the PPTA concentration in the lyotropic solutio...

Synthesis and Application of a Novel Charring Agent Poly(p- Propane Terephthalamide)
关键字:poly(p-propane terephthalamide); intumescent; flame retardant; charring agent
In recent years, intumescent flame retardants (IFR) have attracted increasing attention in the flame retardation of materials because they produce low smoke and toxicity with no corrosive gas generation.

12. Partial phase diagram of poly(p-phenylene terephthalamide) copolymers in sulfuric acid
Copolyaramides with 2,5-di-n-hexyl terephthalic acid residues as comonomers were synthesized. Partial phase diagrams were measured for mixtures with concentrated sulfuric acid in the range between 8 and 20% w/w of polymer. Lyotropic phases were observed, but in comparison to homopoly(p-phenylene terephthalamide) the clearing temperatures are lower and the critical concentrations for the forma...

Structure changes and tensile properties of poly(4,4’-diphenylsulphone terephthalamide-co-3,3’-diphenyl-sulphone terephthalamide) fiber during drawing process
关键字:polyarylsulphonamide fiber,tensile property,crystal structure,drawing technology
The tensile properties of the high-temperature resistant Poly(4,4’-diphenylsulphone terephthalamide-co-3,3’-diphenylsulphone terephthalamide) (PSA) filaments were investigated by the temperature-controlled Stress-strain Tester. The effects of drawing rate, drawing ratio&nb...

Study on the effect of non-solvent on the polymerization of poly(p-phenylene terephthalamide) (PPTA)
关键字:PPTA synthesis; solution viscosity; non-solvent
Polymerization of PPTA (poly (p-phenylene terephthalamide)) is a rapid process even at low temperature, which makes the molecular weight distribution of PPTA wider. In this article, a new method is firstly employed in order to&nbs...

Thermal degradation kinetics of poly (p-phenylene terephthalamide) fiber measured by thermogravimetry
关键字:PPTA,thermal degradation,kinetics parameter,TG
Thermogravimetry analysis (TG) technique has been performed for evaluating the thermal degradation and the kinetics parameters of Poly (p-phenylene terephthalamide) (PPTA) fiber from 25 to 900℃ under nitrogen and air atmosphere. The decomp...

Nonisothermal crystallization kinetics of bio-based semi-aromatic polyamides
关键字:poly(decamethylene terephthalamide),Nonisothermal crystallization kinetics,Biobased,Semi-aromatic polyamides
Semi-aromatic copolyamides PA10T10I and PA10T10F based on bio-based poly(decamethylene terephthalamide) (PA10T) were synthesized by a two-step polycondensation technique. The nonisothermal crystallization of these semi-aromatic polyamides was investigated by differential scanning calorimetry. Avrami theory modified by Jeziorny and Mo equation was used to describe the nonisothermal crystalliza...
