Nitrogen/oxygen permeability of natural rubber, epoxidised natural rubber and natural rubber/epoxidised natural rubber blends

Polymer, 1999
Pure gas transport properties of natural rubber (NR), epoxidised natural rubber (ENR) and their blends have been determined. The permeabilities of the pure polymers and blends were determined with nitrogen and oxygen. The relation between oxygen-to-nitrogen selectivity and the glass transition temperature has been studied.

Molecular Mechanisms of Natural Rubber Biosynthesis.

Annual Review of Biochemistry, 2020
Natural rubber (NR), principally comprising cis-1,4-polyisoprene, is an industrially important natural hydrocarbon polymer because of its unique physical properties, which render it suitable for manufacturing items such as tires. Presently, industrial NR

Natural rubber blends with epoxidized natural rubber

Journal of Macromolecular Science, Part B, 1997
Abstract Blends of NR with ENR have been prepared in full composition following the polymer blend technique. Basic properties (mastication behavior and thermal degradation of each rubber and Mooney viscosity, Flory-Huggins interaction parameters, and cure characteristics of the blends) of the uncured blends were determined, in addition to the reversion,

Natural Rubber

2009
Natural rubber, India rubber and caoutchouc are all names for the solid elastic material isolated, one way or another, from the ‘milk’ or latex of Hevea brasiliensis, and various other tropical plants like Castilloa elastica. Natural rubber and natural rubber products have been known to the ancient cultures of Amazonia and Mesoamerica since time ...

Hydrological consequences of natural rubber plantations in Southeast Asia

Land Degradation and Development, 2020
Since the turn of the century, rubber plantations have been expanding their footprint across Southeast Asia in response to an increasing global demand for rubber products. Between 2000 and 2014, the area cultivated with rubber more than doubled.
