31  US 7,649,118 B2  32  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):  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:  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 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):  wherein Z $^{5 }$is the same or different and each is:  ~  ~~R  R (Yf;!
