CYCLIC BUTYLENE TEREPHTHALATE AND PROMISING FIELD OF APPLICATION

Abstract

Due to its unique characteristics, cyclic butylene terephthalate is used in novel developments of chemical industry. This article represents the review of the latest achievements in the field of processing, structure, properties of cyclic butylene terephthalate, its physical and chemical modifications as well as composites and nanocomposites based on it. In recent years, cyclic butylene terephthalate oligomers have drawn the attention of scientists. The oligomers can be acquired through the chemical reaction of cyclo-depolymerization and used as materials for ring-opening polymerization reactions. This method of polymerization has a variety of advantages compared to a standard method of synthesis polyesters. One of the main advantages of this method includes the capability to make polymerization reactions at standard atmospheric pressure, low required temperature, no side effects and obtaining a completely finished product as an outcome. The unique qualities of cyclic butylene terephthalate make it a promising material to be used as matrix for a variety of nano- and microcomposites and super concentrate. This study analyzes some of the examples of applying CBT as a super concentrate for creating materials like carbon nanotubes, laminated silicates, carbon fibers and glass fibers. In the majority of studies, the addition of nano-sized fillers into CBT leads to amplification of mechanical properties. In the cases of usage as fillers for carbon fibers and glass fibers, the possibility of replacing thermosetting resins with CBT is currently being researched. It could possibly lead to increase in manufacturability of carbon fibers and fiberglass and increase its possible area of application. Cyclic butylene terephthalate can also be used as a viscosity modifier for synthetic rubbers. In this case it can be both plasticizer and enhancing agent.For citation:Chukov N.A., Mikitaev M.A., Ligidov M.Kh., Bashorov M.T., Shogenov V.N., Pakhomov S.I.
