Chapter 1-Literature Review
1.1. Introduction
According to our framework, we played attention to elaborate materials from the renewable resource, such as natural rubber. Thus, the literature survey of concerning works was done.
In this chapter, firstly, various strategies for preparation of precursors, called telechelic oligomers, from high molecular weight natural and synthetic rubbers via controlled degradation feature are described.
Secondly, due to aim of our study being synthesis of polyurethane based conducting composites, hence, polyurethane types, mode of preparation including starting materials and their applications are then defined. Subsequently, the important role of Ionic Liquids, the new generation salts, is demonstrated in the recent researchs as well as in material chemistry. Their structure, unique properties and applications in many areas are expressed, particularly in polyelectrolytes.
Finally, we write about the polyelectrolytes and conducting composites. Types of polyelectrolytes, also ionic liquids incorporated polyelectrolytes, the preparation of polymer conducting composites, especially the employment of polyurethane and elastomers as polyelectrolytes and conducting matrix are represented.
1.2.Telechelic polyisoprene
1.2.1. Definition
The term ‘telechelic’ was proposed originally by Uraneck, Hsieh and Buck for low molecular weight polymers bearing two functional end groups. Nowadays, this term is also applied to oligomers having two or more terminal groups [1].
Telechelic liquid natural rubber (TLNR) can be defined as a low molecular weight oligomer having number average molecular weight approximately 100-10000 and containing reactive terminal groups capable for using in further chain extension and crosslinking. TLNR still consists of isoprene units, basic structure of natural rubber (NR). The main difference from NR is that TLNR has reactive groups at the chain end, as donated by X and Y. X and Y may, or may not, be similar.
