In the formula, the organic group containing a polymeriz- able group, represented by Q$_{1 }$ is not particularly limited as long as a polymerizable group is contained in the group. As the polymerizable group, there can be mentioned, for example, an acrylyl group, a methacrylyl group, a styryl group, a norbornenyl group, a maleimido group, a vinyl ether group or the like. An acrylyl group, a methacrylyl group and a styryl group are most preferred. 

As the bivalent connecting groups represented by L$_{1 }$ and L$_{2}$ , there can be mentioned, for example, a substituted or 25 unsubstituted arylene group, a substituted or unsubstituted alkylene group, a substituted or unsubstituted cycloalkylene group, ---0-, -CO-, and a bivalent connecting group resulting from a combination of two or more of these. 30 

It is preferred for the arylene group to be, for example, one having 6 to 14 carbon atoms. As particular examples of the arylene groups, there can be mentioned a phenylene group, a naphthylene group, an anthrylene group, a phenanthrylene group, a biphenylene group, a terphenylene group and the like. 

The alkylene group and cycloalkylene group are prefer› ably, for example, those each having 1 to 15 carbon atoms.As particular examples thereof, there can be mentioned forms resulting from the abstraction of one hydrogen atom from any oflinear, branched and cyclic alkyl groups, such as a methyl group, an ethyl group, an n-propyl group, an isopropyl group, an n-butyl group, a sec-butyl group, a tert-butyl group, a tert-amyl group, an n-pentyl group, an n-hexyl group, an n-heptyl group, an n-octyl group, an n-nonyl group, an n-de› cyl group, a cyclopentyl group, a cyclohexyl group, a cyclo› pentylmethyl group, a cyclopentylethyl group, a cyclopentyl› butyl group, a cyclohexylmethyl group, a cyclohexylethyl group, a cyclohexylbutyl group and an adamantyl group. 

As substituents that can be introduced in these arylene, alkylene and cycloalkylene groups, there can be mentioned, for example, an alkyl group, an aralkyl group, an alkoxy group, a fluorine atom and the like. 

In one form of the present invention, L$_{1 }$ is preferably a single bond, a phenylene group, an ether group, a carbonyl group or a carbonyloxy group, and L$_{2 }$ is preferably an alky› lene group, an ether group, a carbonyl group or a carbonyloxy group. 

The organic group in the organic group containing a fluo› rine atom, represented by Rf is a group having at least one carbon atom, preferably an organic group containing a car› bon-hydrogen bond moiety. Rfis, for example, an alkyl group substituted with a fluorine atom, or a cycloalkyl group sub› stituted with a fluorine atom. 

It is preferred for the repeating unit (Aal) in its one form to be any ofrepeating units of general formulae (aal-2-1) and (aal-3-1) below.

In general formulae (aal-2-1) and (aal-3-1), 

each ofRa$_{1 }$ and Ra$_{2 }$ independently represents a hydrogen atom or an alkyl group. Each ofRa$_{1 }$ and Ra$_{2 }$ is preferably a hydrogen atom or a methyl group. 

Each ofL$_{21 }$and L$_{22 }$independently represents a single bond or a bivalent connecting group, and has the same meaning as that of L$_{2 }$ mentioned above in connection with general for› mula (aal-1). 

Each of Rf$_{1 }$ and Rf$_{2 }$ independently represents an organic group containing a fluorine atom, and has the same meaning as that of Rf mentioned above in connection with general formula (aal-1). 

It is preferred for the repeating unit (Aal) in its another form to be any ofrepeating units of general formulae (aal-2- 2) and (aal-3-2) below.
