DOWNLOAD EBOOK →A research program was conducted by the Polymer Synthesis Group of the Chemistry Department and the Polymer Materials and Interfaces Laboratory on the theme of new elastomer synthesis. The body of the report described herein subdivided into five areas of discussion. The first deals with a laboratory- scale, low-pressure reactor suitable for living polymerizations and polymer modification studies. This section is followed by a discussion of model homopolymer and block polymer elastomers obtained by hydrogenation. Next, an investigation of a hydrocarbon-soluble organolithium difunctional initiator is described. Elastomers based upon ion-containing block and random copolymers are covered as is a study of the morphology and properties of polyurea(urethane) elastomers. An important conclusion is that saturated elastomers such as butyl rubber and various halogenated derivatives as well as the ethylene-propylene copolymer (EPDM) elastomers should be investigated in high performance applications. Lastly, one concludes that significant additional effort should be conducted in the area of reactive castable elastomers based upon soft, thermally stable flexible segments linked together through poluyrea type hard segments. This approach to castable elastomers has major potential for developing reactive automated fully cured systems of high strength and good abrasion resistance.

DOWNLOAD EBOOK →Thermoplastic elastomers (TPEs), commonly known as thermoplastic rubbers, are a category of copolymers having thermoplastic and elastomeric characteristics. A TPE is a rubbery material with properties very close to those of conventional vulcanized rubber at normal conditions. It can be processed in a molten state even at elevated temperatures. TPEs show advantages typical of both rubbery materials and plastic materials. TPEs are a class of polymers bridging between the service properties of elastomers and the processing properties of thermoplastics. Nowadays, the best use of thermoplastics is in the field of biomedical applications, starting from artificial skin to many of the artificial human body parts. Apart from these, thermoplastic elastomers are being used for drug encapsulation purposes, and since they are biocompatible in many cases, their scope of applications has been broadened in the biotechnological field as well. The present book highlights many biological and biomedical applications of TPEs from which the broader area readers will benefit.

DOWNLOAD EBOOK →Self-healing is a well-known phenomenon in nature: a broken bone merges after some time and if skin is damaged, the wound will stop bleeding and heals again. This concept can be mimicked in order to create polymeric materials with the ability to regenerate after they have suffered degradation or wear. Already realized applications are used in aerospace engineering, and current research in this fascinating field shows how different self-healing mechanisms proven successful by nature can be adapted to produce even more versatile materials. The book combines the knowledge of an international panel of experts in the field and provides the reader with chemical and physical concepts for self-healing polymers, including aspects of biomimetic processes of healing in nature. It shows how to design self-healing polymers and explains the dynamics in these systems. Different self-healing concepts such as encapsulated systems and supramolecular systems are detailed. Chapters on analysis and friction detection in self-healing polymers and on applications round off the book.
