1. the nitrogenous functional rare earth syndiotactic styrenic of a class, is characterized in that:

  • weight-average molecular weight is 1 ×

    10 4-120 ×

    10 4;

    By polymkeric substance total amount mass percent 100%, between nitrogenous functional rare earth syndiotactic polystyrene, normality is not less than 90%;

    The monomer that nitrogenous functional rare earth syndiotactic polystyrene adopts is selected from nitrogenous substituent styrene derivatives, and at least contain a tertiary amine group substituting group, the one in following two kinds of modes is taked in substituent connection;

    (1) substituting group is directly connected in cinnamic ortho position, a position or contraposition;

    (2) substituting group is connected to above the alkyl in vinylbenzene ortho position, a position or contraposition;

    Styrene derivatives contains monosubstituted base, disubstituted or three substituting groups, and substituting group is identical or different.
