アニオン重合又は制御ラジカル重合によるヒドロキシ-ビニル芳香族ポリマー又はコポリマーの製造方法

Title:

アニオン重合又は制御ラジカル重合によるヒドロキシ-ビニル芳香族ポリマー又はコポリマーの製造方法

Document Type and Number:

Japanese Patent JP4563814

Kind Code:

B2

Abstract:

The instant invention relates to a process for the preparation of hydroxy-vinyl-aromatic polymers in particular 4-hydroxystyrene polymers or copolymers by anionic or controlled radical polymerization of the respective monomer, wherein the hydroxy functionality is blocked with a protective group which is subsequently removed by reacting it with a halosilane reagent. The resulting (co)polymers have a narrow polydispersity and are useful for manufacturing photoresists.
