Preparation and Properties of NR Based Ebonite Rubber
The preparation of various samples of ebonite vulcanizates and their physico-mechanical properties have been investigated using standard methods. This work explores the production of ebonite dust, production of ebonite vulcanizates and investigation of the characterisation of the ebonite.

Shape memory NR/PCL bio-based blends, where NR served as the reversible phase and PCL served as the switching phase, were prepared using a melt blending process. Peroxide, besides its role as a cross-linking agent to NR, was used to enhance the compatibility between NR and PCL, which was confirmed via Fourier transform infrared spectra and scanning electron microscopy analyses.

Preparation and mechanical properties
To improve the mechanical properties of the natural rubber based magnetorheological elastomers (MREs), rosin glycerin ester was added into the carrier matrix to enhance wettability and dispersibility of CI particles. Dynamic performance, including shear modulus, loss factor and viscosity of non-vulcanized matrix was measured by rheometer. In comparison

Preparation of synthetic polyisoprene latex and its use
rubber in molecular structure as well as in properties. Synthetic polyisoprene has a slightly lower percentage of cis-1,4 polyisoprene units. Manufacturing polyisoprene (IR) with the desired properties is not a trivial task: the polymerization of isoprene can lead to various repeating units.

Ebonite
Ebonite is a brand name for a material generically known as hard rubber, and is obtained by vulcanizing natural rubber for prolonged periods. Ebonite may contain from 25% to 80% sulfur and linseed oil. Its name comes from its intended use as an artificial substitute for ebony wood. The material has also been called vulcanite, although that name formally refers to the mineral vulcanite. Charles Goodyear's brother Nelson Goodyear experimented with the chemistry of ebonite composites. In 1851 he us
