Inverse Vulcanized Sulfur Polymer Composites From Poultry‐Industry Products and Lignocellulosic Biomass Waste

Journal of Applied Polymer Science, EarlyView.
This work explores the use of various fillers, including eggshell powder, feather meal, peanut hulls, and sawdust to reinforce a base binder GFS90 (comprised of 90 wt.% sulfur, 5 wt.% chicken fat, and 5 wt.% sunflower oil). The resulting composites showed impressive compressive strengths ranging from 15.3 to 36.2 MPa, making them a potential ...

Linear Viscoelastic Behavior of n‐Alkane Diluted Polyethylene Melts: Sorption, Desorption, and Oscillatory Rheometry

Journal of Applied Polymer Science, EarlyView.
This study systematically maps polyolefin dilution dynamics using a homologous series of n‐alkanes. Integrating gravimetric sorption, subsequent controlled desorption, and oscillatory rheometry establishes a precise framework to analyze reduction in viscosity at least for polymer diluent mixtures with polymer concentration > 35% and diluent ...
