To provide a novel alicyclic esterified norbornene carboxylate monomer, polymer thereof and photoresist composition including the polymer as a resin binder and the synthetic methods for the same.
The method of preparing a substituted norbornene represented by general formula (II) (X is a tertiary alicyclic group) comprises (a) the formation of an α,β-unsaturated ester by reaction of an alicyclic alcohol with an α,β-unsaturated compound and (b) the formation of a norbornene by reaction of an α,β-unsaturated ester with a diene. In the process, the step (a) and the step (b) are carried out in succession without isolation of the α,β-unsaturated ester before the reaction with the diene. In an embodiment, the monomer of formula 7 is prepared through the reaction scheme (11).
