| Abstract | Morphology and formation mechanism of poly (4'-oxy-4-biphenylcarbonyl) (POBP) crystals obtained by solution polymerization were firstly treated. It was concluded that the formation mechanism of the bundlelike aggregates of fibrillar crystals in POBP was fundamentally simillar to that in POB whiskers. Secondly the copolymerization effects of m-acetoxybenzoic acid and 4-(4-acetoxyphenyl) benzoic acid on the morphology of POB whiskers were studied. The experimental results strongly supported our proposal for the formation mechanism of whiskers which was consisted of crystallization of oligomers with a critical length as lamellae from solution and solid state polymerizationof oligomers between lamellae. Finally, the formation mechanism of poly (p-oxycinnamoyl) spherical products during solution polymerization was treated. The formation of these spherical products could be understood by overlapped phase diagram of melting depression curve and consolute curve of oligomers-solvent system. |

| Abstract | 本稿は1995年から2004年まで、小・中学生および高校生を対象に実施してきた各種の科学実験体験活動の実践報告である。これらの体験活動は、岡山大学教育学部理科教育講座の教員とそれぞれの研究室に属する学部生・大学院生たちが実践してきたものである。活動の企画、教材開発、活動の運営、子どもたちに対する実験内容の説明から実験指導に至るまで、ほとんどを学生たちの自主性に任せた。教員は学生たちに対する支援に徹することを原則とした。これらの活動を通して得られた成果や、実践活動を行うに当たって、日頃の自然科学の探究活動の大切さについても触れる。 |
