Samuel Emmett Horne, Jr. (1924–2006) was a research scientist at B. F. Goodrich noted for first synthesizing cis-1,4-polyisoprene, the main polymer contained in natural tree rubber, using Ziegler catalysis. Earlier attempts to produce synthetic rubber from isoprene had been unsuccessful, but in 1955, Horne prepared 98 percent cis-1,4-polyisoprene via the stereospecific polymerization of isoprene. The product of this reaction differs from natural rubber only slightly. It contains a small amount of cis-1,2-polyisoprene, but it is indistinguishable from natural rubber in its physical properties.〔(【引用サイトリンク】accessdate=24 March 2014 )〕 The importance of Horne's development of synthetic polyisoprene and polybutadiene is readily seen in the production of these polymers. In 2008, global production of polybutadiene was 2,042,000 metric tons (exceeded only by SBR in capacity and production). Production of polyisoprene was 611,000 metric tons (Russia, 415,000; Asia, 78,000; US, 90,000; Europe, 25,000). In 1980, the ACS Rubber Division honored Horne with the Charles Goodyear Medal. In 1982, he received an honorary doctorate from Emory University.〔(【引用サイトリンク】url=http://www.emory.edu/secretary/documents/HD%20Recipients%20Master%20List%20-%201846%20to%20Present%20%2006.18.13.pdf )〕 ==Personal== Horne was born July 26, 1924, in Jacksonville, Florida He grew up in Tampa, Florida. He married Sue Ross in 1949. They had four children. He showed interest in chemistry at a young age. When he was five or six years old, he and a friend played with a chemistry set. Although the experiments sometimes led to unpleasant odors and other problems, his parents nevertheless encouraged the young Horne to pursue his interest in chemistry. Horne died on February 4, 2006, in Columbus, Ohio. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Samuel E. Horne, Jr.」の詳細全文を読む スポンサード リンク
