Abstract
Message aimed at improving the mechanical properties and thermal behavior of the material polystyrene was prepared three mixtures of
1 - Poly Styrene + Styrene-Butadiene Rubber
2 - Poly Styrene + Styrene-Butadiene Rubber
3 - Poly Styrene + Styrene-Butadiene Rubber < br> mixtures were prepared in a manner to confuse Ansharri
The letter includes the four main chapters: -
1 - a general introduction to polymers and structural composition and properties of its general
2 - How to mechanical characterization using ultrasonic wave technology and characterization of polymers using DSC technique
3 - materials used and how to mix and cast and methods of measuring molecular weight, density, mechanical properties and thermal properties and conditions of measurement
4 - results that have been reached.
