A Micro-Mechanically Based Continuum Model for Strain-Induced Crystallization in Natural Rubber

Recent experimental results show that strain-induced crystallization can substantially improve the crack growth resistance of natural rubber. While this might suggest superior designs of tires or other industrial applications where elastomers are used, a more thorough understanding of the underlying physics of strain-induced crystallization in natural rubber has to be developed before any desig...

Strain-induced 13C chemical shift change of natural rubber

We investigated the effect of deformation of natural rubbers (NR) resulting from the high centrifugal pressure of fast magicangle spinning (MAS) on 13C NMR spectra. The solid state 13C MAS NMR spectrum with high-power 1H dipolar decoupling (DD) of NR presents liquid-like, very narrow signals (full width at half height, FWHH, is less than 10 Hz). However, the static state 13C DD NMR spectrum of ...

An investigation on chloroprene-compatibilized acrylonitrile butadiene rubber/high density polyethylene blends

Blends of acrylonitrile butadiene rubber/high density polyethylene (NBR/HDPE) compatibilized by Chloroprene rubber (CR) were prepared. A fixed quantity of industrial waste such as marble waste (MW, 40 phr) was also included. The effect of the blend ratio and CR on cure characteristics, mechanical and swelling properties of MW-filled NBR/HDPE blends was investigated. The results showed that the ...

The Cyclization of Natural Rubber

The effects of solvent, temperature, time, weight percent of catalyst on the rate and mechanism of cyclization of natural rubber (NR) was studied in toluene and xylene solutions having tin tetra chloride catalyst (SnCl4). Iodometric titration show, with 8% SnCl4 (based on polymer weight) cyclization occurs, leaving 27.4% of the total unsaturation. Infrared spectra of c...

Comprehensive Kinetic Numerical Model for NR and High-Cis Poly-Butadiene Rubber Blends

A simple but robust kinetic mathematical model to predict the mechanical/thermal behaviour of NR and highcis polybutadiene rubber blends is presented. The benchmark blend is a 70% NR with 30% high-cis polybutadiene blend vulcanized in presence of sulphur at 1 phr and single accelerants TBSS or DPG at concentrations equal to 1-0 and 0-1 respectively. Experimental rheometer curves are at disposal...
