Thermal Stability of Aliphatic and Semiaromatic Polyamides: Tailoring the Choice of Isothermal Aging Temperature by Using Kinetic Models of Degradation

Journal of Applied Polymer Science, EarlyView.
Thermogravimetric analysis was performed to study the degradation of aliphatic and semiaromatic polyamides intended for the electrical insulation of future electric aircraft. Using the TGA results, the Flynn and Wall method and Toop's model, the activation energies for the degradation processes were calculated, and kinetic models of the degradation ...

Cyclic Processability of Functional Liquid Crystalline Epoxy Networks via Dynamic Ester Bonding

Journal of Applied Polymer Science, EarlyView.
This work reports the successful reprocessing of liquid crystal epoxy networks through two distinct modes—welding of clean breaks and reconstitution from shredded material—without significant loss of functionality. Thermal and mechanical characterization shows stability in the shape memory behavior and glass transition temperature over multiple ...

Concentration‐Dependent Lamellar Organization and Structure–Property Relationships in Melt‐Processed EVA/Cloisite 20A Nanocomposites

Journal of Applied Polymer Science, EarlyView.
Cloisite 20A content tunes the structural and mechanical response of melt‐processed ethylene‐vinyl acetate (EVA) nanocomposites. Expanded basal spacings at 5.0 and 7.5 wt% clay are consistent with polymer‐chain intercalation within ordered clay domains.

Polyurethane Foams From a Triblock Copolymer Polyol With CO2‐Derived, High‐Tg Polycarbonate Segments

Journal of Applied Polymer Science, EarlyView.
Polyurethane foam (PUF) properties are tuned by incorporating polyol with 0–15 wt% CO2‐derived poly(cyclohexene carbonate) (PCHC) segments (Tg = 104°C). Network PUFs are synthesized using CO2‐derived triblock copolymer polyol with PCHC hard segments and a polycaprolactone soft segment.
