Process for the preparation of hydroxy-vinyl-aromatic polymers or copolymers by anionic or controlled radical polymerization |
| 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 in a hydrogenation process. The resulting (co)polymers have a narrow polydispersity and are useful for manufacturing photoresists. |
