Process for preparing polyhydroxystyrene derivatives |
| abstract |
The present invention provides a process for preparing a polyhydroxystyrene derivative, comprising adding polyhydroxystyrene to an alkaline alcohol solution to form a homogeneous polyhydroxystyrene solution; and reacting the polyhydroxystyrene solution with an ester to obtain the polyhydroxystyrene derivative. The obtained polyhydroxystyrene derivative is suitable for use as the resin component of a photoresist. |
