Determination of Gel Content (C-C Crosslink) in Polybutadiene Rubber by Differential Scanning Calorimetry

open access: yes, 2014
Due to the gel formation in polybutadiene and some of the problems raised in rubber industry such as groove cracking in products, quantification of the gel content and identification of the microstructure of butadiene elastomer is extremely important. In

From shifting agriculture to sustainable rubber agroforestry systems (jungle rubber) in Indonesia: a history of innovations processes. [PDF]

open access: yes
The aim of this chapter is to describe changes in the Indonesian jungle rubber system from the angle of the production of innovation by farmers themselves (indigenous knowledge) and the process of integration of external technical innovations in an ...

THE RUBBER SHOWCASE IN SUMATRA [PDF]

open access: yes
As with cocoa a combination of available land and centres with fairly dense population is a prerequisite for a boom. But in the case of rubber the boom has been far more progressive than that for cocoa due to 3 main factors.

A Peroxide Curing Butyl Rubber

open access: yes, 1969
The reactions of peroxides with polymers have been studied for some time. They form an extensive part of vulcanization technology. Two types of reactions are generally recognized, those leading to crosslinking between polymer chains and those leading to ...

The viscoelastic properties of rubber under a complex loading

open access: yes, 2010
PhDThis thesis aims to explore the effect of pre-strain on the viscoelastic behaviour of rubber materials. There are various conflicting theories in the literature regarding the strain dependence and resulting anisotropy of the viscoelastic behaviour ...

Crosslink Density in Polybutadiene

open access: yes, 1959
1. A method has been developed for the measurement of crosslink density of diene polymers. This method, which involves the use of radioactive chain transfer agents, is applicable to ungelled polymer prepared under a wide variety of conditions so that any

Modification of Butadiene -Acrylonitrile Rubber/ Poly(Vinyl Chloride) Blend Using Natural Rubber, Styrene-Butadiene Rubber, and Polybutadiene Rubber

open access: yes, 1987
Natural rubber, styrene-butadiene rubber, and polybutadiene rubber were used to replace part of the butadieneacrylonitrile rubber in a 70/30 butadiene-acrylonitrile rubber/ poly(vinyl chloride) blend. Such replacement up to 15% of the total weight of the

The Structure of Cyclized Polybutadiene

open access: yes, 1958
Polybutadiene was cyclized with sulfuric acid under rather drastic conditions. The cyclization was confirmed by the decrease of unsaturation and the change of physical properties. The low degree of unsaturation of cyclized polybutadiene, as determined by
