[Structural Unit Represented by General Formula (a3-13)] 

In general formula ( a3- l 3 ), R is the same as defined for R in general formula (a3-l). 03 

P represents ----C(=O)-O- or ----C(=O)-NRn- (wherein Rn represents a hydrogen atom or an alkyl group of 1 to 5 carbon atoms), and preferably -C(=O)-O-. The alkyl group for Rn is the same alkyl group as described above for R. 

The linear hydrocarbon group for W $^{03 }$preferably has 1 to 10 carbon atoms, more preferably 1 to 5 carbon atoms, and still more preferably 1 or 3 carbon atoms. 

The linear hydrocarbon group for W$^{03 }$may have a substitu- ent (a) other than -OH, -COOR, -CN, -SO$_{2}$NH$_{2 }$ and ----CONH$_{2}$ . Examples of the substituent (a) include an alkyl group of 1 to 5 carbon atoms, an aliphatic cyclic group (mono› cyclic group and polycyclic group), a fluorine atom and a fluorinated alkyl group of 1 to 5 carbon atoms. The aliphatic cyclic group for the substituent (a) preferably has 3 to 30 carbon atoms, more preferably 5 to 30, still more preferably 5 to 20, particularly more preferably 6 to 15, and most prefer› ably 6 to 12. As the aliphatic cyclic group, a group in which two or more hydrogen atoms have been removed from a monocycloalkane or a polycycloalkane such as a bicycloal› kane, tricycloalkane or tetracycloalkane can be used. Specific examples include groups in which one or more hydrogen atoms have been removed from a monocycloalkane such as cyclopentane or cyclohexane; and groups in which one or more hydrogen atoms have been removed from a polycycloal› kane such as adamantane, norbomane, isobornane, tricyclo› decane or tetracyclododecane.
