In formulae (Ila) to (Ile), RII_$_{1}$ , RII_$_{2}$ , L$_{1 }$ and L$_{2 }$ have the same meanings as in formula Examples of the organic group of X 3 are the same as those of the organic group for X in formula (I). 

Examples of the divalent linking group ofY $_{2 }$are the same as those for L$_{1 }$ in formula (II). The ring structure which may be formed by combining RII_$_{2 }$ and R$_{2 }$ may be monocyclic or polycyclic and may be an alicyclic hydrocarbon group or an aryl group. Examples of the alicyclic hydrocarbon group are the same as those of the alicyclic moiety which can be con- tained in the organic group of X$_{1 }$ described later. Preferred examples of the aryl group include a phenyl group, a xylyl group, a toluyl group, a cumenyl group, a naphthyl group and an anthracenyl group. 

Y$_{5 }$ represents a linking group represented by ---0-, -S- or ----C(Rm)CRm)-. Rm and R,, each independently represents an alkyl group, a cycloalkyl group, a halogen atom, an ary 1 group, an aralky 1 group, an alkoxy group or an acy loxy group, provided that the alkyl group and the aralkyl group each may have an intervening linking group represented by -0-, -S-, -CO$_{2}$-, -CO-, -S0 2 - or -SO-. 

u represents 0 or 1, p’ represents an integer of0 to 6, q’ each independently represents an integer of Oto 4, r’ represents an integer of0 to 5, s’ represents an integer of0 to 5, and t’ each independently represents an integer of 0 to 4, provided that r+s is 5 or less. 

The repeating unit represented by formula (II) is more preferably a repeating unit represented by any one of formu› lae (Hal) to (IIel ):

In formulae (Hal) to (IIel), 

RII_$_{1}$ , RII_$_{2}$ , Li, L$_{2}$ , X1, X$^{2 }$andX$^{3 }$each has the same mean› ing as above, 

Y $_{6 }$ represents a linking group represented by -CH$_{2}$ - or ----CO-O-, 

v represents 0 or 1, and 

s" each independently represents an integer of0 to 4. 

Specific examples of the repeating unit represented by formula (II) are set forth below, but the present invention is not limited thereto.
