Title:
バルク密度が高い環状オレフィン高分子の製造方法及び、これによって製造された環状オレフィン高分子
Document Type and Number:
Japanese Patent JP4459908
Kind Code:
B2
Abstract:
A method for preparing a cyclic olefin polymer is described. The method includes polymerizing cyclic olefin monomers or a cyclic olefin monomer with ethylene to prepare a cyclic olefin polymer solution; slowly adding a non-solvent drop wise to the cyclic olefin polymer solution to precipitate a cyclic olefin polymer; and filtering and drying the precipitated cyclic olefin polymer. In addition, the cyclic olefin polymer prepared using this method is described. According to the present invention, a spherical cyclic olefin polymer having a high bulk density can be easily separated from the cyclic olefin polymer solution by precipitation.
