To provide a radical curable siloxyl group-containing polyvinyl alcohol polymer which has common characteristics such as coating film formability and transparency, has high solubility in an organic solvent, therefore, has excellent handleability for a fluid material, and further has both of the solvent resistance and formability of an obtained coating film.SOLUTION: The modified radical curable polyvinyl alcohol polymer has both of a silicon-containing group into which a siloxyl group-containing side chain and an acryloyloxy group-containing side chain are introduced by modification, and an acryl group.SELECTED DRAWING: None 【課題】皮膜形成性や透明性等の一般特性を有し、有機溶媒への溶解性が高いことから液状材料としての優れた取り扱い性、更に得られる皮膜の耐溶剤性、成形性を併せ持つラジカル硬化性シロキシル基含有ポリビニルアルコール系重合体を提供する。【解決手段】変性によってシロキシル基含有側鎖およびアクリロイルオキシ基含有側鎖を導入したケイ素含有基、アクリル基をともに有する変性されたラジカル硬化性ポリビニルアルコール系重合体。【選択図】なし
