Three unvulcanized rubber systems were used for this study; two butyl rubbers (poly[isobutylene-co-isoprene]) and a polyisoprene
Tokyo, June 1, 2012 - (JCN) - Bridgestone has successfully polymerized high-cis polyisoprene
(IR) synthetic rubber from isoprene provided by Ajinomoto, a partner in synthetic rubber development for tires.
The manufacturer of LifeStyles condoms is expanding size options and product choices for users suffering from latex allergies with the first large polyisoprene
condom, according to company officials.
Topics include variation of inhibited oxidation parameters in the range of phase transition; kinetics of sulfur vulcanization of 1,4-cis- polyisoprene
by differential scanning calorimetry; influence of electric and mechanical forces on the oxidation kinetics and electrocoductive polyisoprene
composition properties; physicochemical properties of a regulatory peptide from the bovine eye lens and effects on cataract development; and regulatory proteins from the mammalian liver that display biological activity at ultra low doses.
It is one of few species of higher plants that have been shown to produce polyisoprene
in the all trans-1, 4 configuration, which is called EU rubber.
Showing styrenic block copolymers (SBCs) and polyisoprene
Some of the alternative materials include nitrile rubber, polyurethane, neoprene, polyisoprene
, and chloroprene.
Mixing polystyrene, the stuff of plastic cups, and polyisoprene
, a material used for making automobile tires, is like trying to combine oil and water.
The liquid silicone rubber (LSR) segment is also noting growth - attributed to technological and material advances, and the fact that manufacturers are seeking to replace polyisoprene
in medical devices.

Latex Articles with Improved Intraparticle and Interparticle Crosslinks.
Open Competition: The right to a state contract for construction and installation work at the site fluorosiloxane monomers for the project: Technical re-trial production of siloxane, fluorosiloxane and acrylate monomers, 3,4 polyisoprene
, low molecular weight hydrocarbon rubbers; epoksiuretanovyh and acrylate rubber, rubber compounds and sealants Federal State Unitary Enterprise Order of Lenin and Red Banner of Labor Research Institute of Synthetic Rubber Academician SV Lebedev (FSUE NIISK), St.
Before and after E-beam exposure, molecular weight was determined for each SBCs and homopolymer of polyisoprene
and polybutadiene using size exclusion chromatography (SEC) to ascertain whether chain scission or crosslinking were the predominate reaction pathway.
