    In this paper, we will report the industrial production method and properties of polyolefin elastomers (POEs) and their applications. Most POEs are random copolymers of ethylene-co-1-butene (EB) and ethylene-co-1-octene (EO). These POEs are generally produced by solution polymerization in a hydrocarbon solvent with unique catalyst systems that enable efficient co-monomer incorporation and ability to attain lower crystallinity than traditional polyolefin products. Their physical properties are greatly dependent on co-monomer type, co-monomer content and molecular weight. POEs are used in a variety of applications, including impact modifiers for automotive polypropylene (PP) based compounds. This paper will further describe new POEs including olefin block copolymers (OBCs) and super high flow POEs.

    Silicone Rubber (SR) is made from silicone polymers and generally added reinforced fillers to improve the strength. SR has been used for various applications in different markets from general purpose to food contact, infant care, home appliance, healthcare, transportation, electric power, electronics, lighting and so on. In this paper, manufacturing methods of SR are reported.

    Homogeneous catalyses promoted by transition metal complexes such as cross coupling reaction, Mizoroki-Heck reaction, Tsuji-Trost allylation reaction,functionalization of C-H bond, Sharpless oxidation reaction, and some recent topics related to organotransition metal complexes are described. Mechanistic aspects of these reactions are also discussed based on the fundamental reaction patterns of organotransiton metal complexes. Future perspectives of organotransition metal catalyzed reactions are also described.
