Rheological Characterization and Multi‐Regime Viscosity Modeling of Diluted Polyethylene Mixtures

Polymer Engineering &Science, EarlyView.
This study maps the flow behavior of low‐density polyethylene in a recycling solvent from dilute solutions to entangled melts. By integrating time–concentration and time–temperature superposition, and coupling three complementary rheometry methods, a unified semiempirical model accurately predicts steady‐shear viscosity over nine decades of viscosity ...

Melt and Cold Crystallization Behavior of Poly(Lactic Acid) With Different Molecular Weights and Its Influence on Mechanical, Viscoelastic, and Tribological Properties

Polymer Engineering &Science, EarlyView.
Modifying the crystallinity of PLA and its properties through annealing. ABSTRACT The melt and cold crystallization behavior of two PLA grades with different molecular weights was investigated using various DSC analyses. During isothermal melt crystallization, PLA with lower molecular weight exhibited faster crystallization kinetics across different ...

In Situ Curing‐Enabled 3D Printing of Continuous Fiber‐Reinforced Thermosetting Composites

Journal of Polymer Science, EarlyView.
In situ curing‐enabled the 3D printing of continuous fiber/thermoset composites, which were reviewed. Particularly, four types of in situ curing, were discussed, including Radiation‐induced curing, photothermal curing, electrothermal curing, and frontal polymerization. AI‐integrated printing was also analyzed.

Molecular, rheological, and crystalline properties of low-density polyethylene in blown film extrusion

, 2007
The molecular weight and its distribution, degree of long chain branching and cooling rate strongly influence crystallinity during processing, which in turn determines the processability and the ultimate properties of the blown film. Generally a decrease
