The invention relates to the technical field of high polymer materials, and discloses a copolymer and a preparation method and application thereof, and a polar side chain-containing copolymer and a preparation method and application thereof. The copolymer comprises 43 to 94.5 wt% of a conjugated diene chain segment, 0 to 56.5 wt% of a styrene chain segment and 0.1 to 20 wt% of a halogenated alkyl styrene chain segment. The copolymer comprises a halogenated alkyl styrene chain segment capable of providing halogen, so that the copolymer has polar reaction activity, a polar monomer can be grafted on a main chain of the copolymer through ATPR reaction, and controllable adjustment of the grafted polar side chain content and the chain length can be realized; the compatibility between the copolymer and a polar filler and between the copolymer and a polar polymer can be remarkably improved, so that the composition containing the copolymer and/or the polar side chain-containing copolymer has improved mechanical properties, wet skid resistance and heat generation performance, and can be used in the fields of high-performance tire manufacturing, plastic modification and the like.
