Research Abstract	まずスピロオルトカーボナート(SOC)ないしはスピロオルトエステル(SOE)構造を持つビニル型モノマーを設計し、種々のコモノマーとの共重合反応を行うことにより、同構造を側鎖に有するコポリマーを合成し、その架橋反応と体積変化挙動を検討した。具体的には、合成したコポリマー中のコモノマーユニット、架橋基(SOCないしはSOE)、共重合組成比の影響を検討した。結果は以下の通りである。1)SOCの場合にはその重合時の体積膨張性に伴って共重合体中のSOC組成が高いほど架橋反応時の収縮が低減され、SOC組成の高いコポリマーでは膨張性が確認された。また、組成比と体積変化の関係の傾きはコモノマー構造の影響を大きく受けることも明らかとなった。2)SOEの場合にはその重合時の体積非収縮性により、共重合組成比に関わらず架橋時の体積変化が0〜4%程度と常に小さな値を示し、体積非収縮性を発現させるために組成比を厳密にコントロールする必要性がないことが明らかとなった。これにより、架橋体の他の物性をコントロールする上で架橋基以外の要因を主として考慮すれば良いことが分かる。また、SOCの高い体積膨張性に着目し、同構造のみからなるオリゴマーを合成し、その架橋反応についても検討した。このオリゴマーはその剛直な構造に基づいてナノレベルでの高い配向性を示すことから、CHOからなるポリマーとしては非常に高い密度を示す。これが架橋反応によりアモルファス化すると架橋により分子間が共有結合で結合されるにも関わらず、低密度化することが明らかとなった。また、SOC2量体の重合反応前後をSEMで観察したところ、部分的な架橋が進行した際には架橋前に存在した空隙が減少している様子が観察され、上記の現象を支持することができた。
