NEW MATERIAL:An electron acceptor polycondensation high polymer of formula I: (R1 is H, <= 8C alkyl, aryl, aralkyl, alicyclic, methylol derivative; Cm is a connection part having one or more atoms; FLac is an electron acceptor group having fluorene nucleus as a fundamental skeleton; X and Y are carbonyl or acid amide group capable of forming urethane group including diol oxygen; R2 is <=C bifunctional organic residue; n is a polycondensation degree of the polymer, > 10). USE:Electrography. (A photoconductive high polymer of the p-type and n-type photoconductor characteristics capable of expanding the range of combination with the toner material.) PROCESS:A propanediol of formula II: (R1'' is R1; Cm'' is Cm) having a 4,5,7- trmitro-9-oxo-2-fluorenyl group is reacted with a diisocyanate.
