The invention discloses a spiro-containing polymer as well as a preparation method and application thereof. The structure of the polymer is shown as a formula (I). Wherein x is 0.05-0.5, and n is a natural number greater than or equal to 5; r1 and R2 are respectively and independently selected from C1-C8 alkyl, phenyl, phenyl substituted by C1-C6 alkyl, naphthyl or naphthyl substituted by C1-C6 alkyl; r < 3 >, R < 4 >, R < 5 >, R < 6 >, R < 8 >, R < 9 >, R < 10 > and R < 11 > respectively represent substituent groups at any position on a benzene ring; r3 is selected from hydrogen or C1-C6 alkyl; r < 4 > and R < 5 > are respectively and independently selected from hydrogen, C1-C6 alkyl, diphenylamino or dibenzopyrrolyl; r6 is selected from hydrogen or C1-C3 alkyl groups; r7 is selected from alkyl groups with 1 to 15 carbon atoms; r8 and R9 are respectively and independently selected from hydrogen or C1-C6 alkyl; r10 is selected from hydrogen or C1-C5 alkyl; and R11 is selected from hydrogen or C1-C3 alkyl grou
