and the like. 

In those norbomene derivatives having fluorine-containing alcohol structure, Rt4 is selected from those which are the same as RF mentioned in the above-mentioned norbornene 25 derivatives having fluorine-containing ketone structure. Pre› ferred examples thereof are also the same as those of RF. 

R $^{3 }$is selected from Hor hydrocarbon groups having 1 to 10 carbon atoms, for example, an alkyl group or aryl group having 1 to 10 carbon atoms or an alkyl group which has 1 to 10 carbon atoms and may have ether bond. Examples of preferred R $^{3 }$are:

and the like. 

The third of the norbomene derivatives of the present invention is one in which a moiety of fluorine-containing tertiary alcohol structure: 

<img src='content_image/930598.jpg'>

is bonded directly to the norbornene backbone, and is a novel compound which is not disclosed in patent publications and technical literatures. 

Such a novel norbomene derivative is one having a fluo- rine-containing tertiary alcohol structure represented by the formula (9):

wherein Z $^{5 }$is the same or different and each is:

in which Rt4 and RF are the same or different and each is a fluorine-containing alkyl group having 1 to 10 carbon atoms or a fluorine-containing alkyl group which has 1 to 10 carbon atoms and ether bond; Y is the same or different and each is H, F, Cl, an alkyl group having 1 to 10 carbon atoms or a fluorine› containing alkyl group which has 1 to 10 carbon atoms and may have ether bond; R is the same or different and each is H or an alkyl group having 1 to 10 carbon atoms; n is 0 or an integer of from 1 to 5; mis an integer of from 1 to 5; nl is an integeroffroml to5;m+n1=6. 

The norbornene derivative may have one or a plurality of moieties Z $^{5 }$of fluorine-containing tertiary alcohol structure, and particularly the norbomene derivative having one or two moieties is preferred. 

For example, there are a norbomene derivative having a fluorine-containing tertiary alcohol structure represented by the formula (10):

wherein Rf4 and RF are the same or different and each is a fluorine-containing alkyl group having 1 to 10 carbon atoms or a fluorine-containing alkyl group which has 1 to 10 carbon atoms and ether bond; 

Y is the same or different and each is H, F, Cl, an alkyl group having 1 to 10 carbon atoms or a fluorine-containing alky 1 group which has 1 to 10 carbon atoms and may have ether bond; R is the same or different and each is H or an alkyl group having 1 to 10 carbon atoms; n is 0 or an integer of from 1 to 5, and 

a norbornene derivative having a fluorine-containing alcohol structure represented by the formula (11):
