PURPOSE: Provided is a new polymer emitting blue light as light-emitting display device, which is fluorenene based derivative by performing a methylene of fluorenone based derivative having steric hindrance. CONSTITUTION: A preparation method of co-polymer emitting blue light comprises the following steps: (i) performing methylenation of 9-fluorenone of formula 1 and derivative thereof by using Tebbe to 9-fluorenene of formula 2 and derivative thereof; (ii) obtaining a living co-polymer whose mole number and molecular weight of fluorene based unit are controlled by co-polymerizing the 9-fluorenene and derivative thereof with vinyl based monomer through using alkyl lithium and alkali metal naphthalenide initiator in the presence of polar or non-polar solvent; (iii) obtaining a block co-polymer by co-polymerizing the living co-polymer obtained in step (ii) with monomer for manufacturing polymer electrolyte, R2 is H, F, Cl, N(CH3)2, OSi(CH3)2(t-Bu), R3 is H or Cl, R2 and R3 are not always same, R4 and R5 are H, F, N(CH3)2, OH or NH2 independently.
