Kinetics of anionic polymerization of β‐myrcene in hydrocarbon solvents
Polymer International, EarlyView.The process of anionic polymerization of β‐myrcene in hydrocarbon solvents was examined by kinetic studies and quantum chemical calculations. Abstract The kinetics of anionic polymerization of β‐myrcene initiated by sec‐butyllithium were examined in saturated and unsaturated hydrocarbon solvents, i.e. cyclohexane, cyclohexene, 4‐vinylcyclohexene and dl‐

Irreversible hardening of a colloidal gel under shear: The smart response of natural rubber latex gels. [PDF]
Journal of Colloid and Interface Science, 2019 Natural rubber is obtained by processing natural rubber latex, a liquid colloidal suspension that rapidly gels after exudation from the tree. We prepared such gels by acidification, in a large range of particle volume fractions, and investigated their ...

Hevea brasiliensis seeds: A novel sustainable feedstock for ethanol production
Vietnam Journal of Chemistry, EarlyView.Abstract The rubber tree (Hevea brasiliensis) is cultivated on a large scale mainly for the extraction of latex in Brazil and Southeast Asia, also generating large quantities of seeds. These seeds currently do not have large‐scale applications and may thus be considered as a residue.

Transformation of the Agrarian Landscape and Hope in the Central Kalimantan Peatlands
Asia Pacific Viewpoint, EarlyView.ABSTRACT In Kalimantan, Indonesian Borneo, agrarian state programs and corporate strategies seek to transform indigenous Ngaju Dayak into sedentary farmers. Focusing on the notion of transformation, the paper traces whether and how rural people can engage in struggles against structural injustices.

Contact Dermatitis, EarlyView.Disposable glove reuse reduced chemical protection during repeated hair‐dye exposure. Under ASTM F739 testing, natural‐rubber‐latex deteriorated rapidly after one reuse, whereas neoprene performed better initially but also declined over repeated cycles. Wash type had no significant effect. These findings support single‐use only and discourage the reuse

Electrochemical Science Advances, Volume 6, Issue 4, August 2026.ABSTRACT Flow capacitive deionisation is an advanced electrochemical technology for water purification and energy‐related applications. It represents a viable alternative to conventional desalination methods due to its low operating voltage, continuous electrode regeneration, and stable performance under moderate‐to‐high salinity conditions. The use of

Film from Mixtures of Natural and Synthetic Rubber Latex. Physical Properties
, 1952 When tested in a single standardized procedure for cast latex films, the type of synthetic-rubber latex employed in latex blends containing 70 per cent or more natural-rubber latex had little effect on the stress-strain properties of the mixture.

Environmentally safe preservation and stabilization of natural rubber latex in an acidic environment
SPE Polymers, 2023 Natural rubber is an indispensable raw material that supplies about half of the world's rubber consumption. The latex that is extracted from the trees is composed of polyisoprene rubber, proteins, sugars, amino acids, lipids, and minerals.
