Gutta Percha

Gutta percha the trans-14-polyisoprene of botanical origin was once the exclusive material for a variety of objects such as insulative covering of submarine cables chemical-resistant devices golf balls and denture and dent fillers. This book traces the journey of this unique polymer which played a role as precursor to the synthetic thermoplastics emergence in 20th century. (The appendices briefly review the history of Xylonite (Celluloid) and Amber & Copal is briefly reviewed). 植物由来のトランス-14-ポリイソプレンであるグッタパーチャは，かつて海底ケーブルの絶縁被覆，耐薬品性装置，ゴルフボール，義歯・歯科用フィラーなどの為の唯一無二の材料であった。本書は20世紀に出現した合成熱可塑性プラスチックの前身としての役割を果たしたこのユニークなポリマーの「旅」を辿る（付章ではザイロナイト（セルロイド）並びに琥珀及びコパルの歴史を簡単に振返る）。ContentsForeword by Prof. Malcolm M.
