Copolymerization
This chapter primarily focuses on chain growth copolymerization. Copolymers composed of two monomers can be classified according to the relative arrangement of the two types of monomer units along the chain or, in other words, according to the monomer distribution. For linear chains, one can have four types of copolym…
Application of External Fields to Technology of Metal‐Matrix Composite Materials
This chapter contains sections titled: Introduction Preliminary Considerations Experimental Results Conclusions Acknowledgements
Polymer Blends
Polymer modification processes based on simple mechanical mixtures of two or more polymers originated a new class of materials called polymer blends. The performance of polymer blends depends on the properties of each polymer in the blend, their content, and morphology. Polymer blends can be classified into the follow…

Free Radical Polymerization
This chapter deals with the description of the free radical polymerization (FRP) mechanism including initiation, propagation, and bimolecular termination reaction steps. Additional reactions such as chain transfer are introduced to improve the process description. In FRP, the progress of the reaction is measured in te…
Introduction to Polymers and Polymer Types
Polymers are very large molecules, or macromolecules, formed by the union of many smaller molecules. This chapter gives an introduction to polymers and polymer types. First, it talks about mechanical and rheological properties of different types of polymers, polymer states, and molecular weight distribution. Next, the…

This chapter contains sections titled: Introduction Experimental Procedure Results Conclusions Acknowledgments
Thermosetting Polymers
Thermosetting polymers (also called thermosets) are a family of plastics characterized by the fact that they are formed starting from a liquid solution that irreversibly leads to a solid material during a heating step. This chapter focuses on some aspects of the chemistry of epoxy polymers because it provides examples…
Structure and Mechanical Properties of Polymers
This chapter talks about structure of polymer chains, and mechanical properties of polymers and polymer composites. Properties of polymers, as in the case of any chemical compound, are highly dependent on the structure of the polymer chains and the molecular weight resulting from the number of units covalently bonded.…
Principles of Polymer Processing
The chapter talks about principles of polymer processing. Most polymeric raw materials are available in the solid state as granules, flakes, or powders. Solid raw materials have to be transformed into a fluid or plastic state, which is accomplished by heating. Once in the plastic or fluid state, the material is shaped…
Trenje i trošenje nisko temperaturno nanesene TiN prevlake klizanjem u suhim uvjetima pri različitim brzinama
Original scientific paperIn this research the influence of sliding speed on friction and wear of TiN coatings during dry reciprocating sliding against alumina ball was studied.Additionally, in order to find the optimum sliding speed, the coatings with different surface roughness were tested.The range of surface roughn…
ESTUDO DAS PROPRIEDADES ANTIOXIDANTES DE DIFERENTES FTALOCIANINAS
O estresse oxidativo esta envolvido na etiologia de diversas doencas cronicas, incluindo doencas cardiovasculares, diabetes, câncer, e doencas neurodegenerativas. A partir desta perspectiva, nos avaliamos as possiveis capacidades antioxidantes de cinco diferentes ftalocianinas (PCs), consistindo de 4 metaloftalocianin…
IRP P-Q THEORY FOR ACTIVE POWER FILTERS. LIMITATION OF APPLICATION
The articled is devoted to «p-q» instantaneous reactive power theory. Two facts of critics of this power theory is analyzed. The first critical fact is about wrong current compensation in case of active current filter which works in power net with unbalanced voltage. It was shown that coordinate transform matrixes don…
