ABSTRACT

This article reviews different types of high-temperature thermoplastic elastomers and thermoplastic vulcanizates from rubber-plastic blends. Preparation, structure, and properties of these materials are discussed briefly. Strategies to further improve the high-temperature performance of these materials are presented herein. A synopsis of the applications of these high-performance materials in the automotive industry is reported, pointing out the gaps to motivate potential research in this field.

ABSTRACT

Raman spectroscopy is potentially useful in the analysis of polymer composites filled with carbon materials. These carbon materials that display strong resonance-enhanced Raman scattering effects give rise to strong bands even if used at very low filler loading, thus making Raman spectroscopy one of the most important techniques for the analysis of various properties of the composites. Factors that influence the Raman signal are presented and discussed for correct acquisition and interpretation of the spectra of polymer composites. Special attention is given to the characterization of the polymer–filler interface, which has been shown to play a crucial role in the extent of property improvement of the polymeric matrix.

ABSTRACT

Vulcanization or curing is one of the most important processes in rubber technologies. During this process, plastic rubber compounds by parallel and subsequent physical and mainly chemical reactions change into highly elastic products—vulcanizates. The fundamental goal of curing is forming chemical cross-links between rubber macromolecules, which leads to the formation of a three-dimensional network or rubber matrix. A number of curing systems have been introduced in cross-linking of elastomers; each system has its own characteristics and composition; therefore, vulcanizates with different properties also can be prepared. We characterize organic peroxides as curing agents and their decomposition mechanisms and characteristics and bring a detailed view to understanding mechanisms between peroxides and different types of rubber matrices. Then, we focus on the classification and characterization of co-agents used in peroxide cross-linking and explain the mutual interactions and reaction mechanisms between peroxide, co-agents, and rubber matrices in relation to the properties of prepared materials. Finally, the drawbacks and the main features of final cross-linked materials are outlined.
