摘要（英）：

The invention relates to the field of materials and provides a fluorosilicone epoxy and polystyrene tetrablock polymer which is polydimethylsiloxane-epoxy-b-polystyrene-b-polymethyl methacrylate. A preparation method of the fluorosilicone epoxy and polystyrene tetrablock polymer comprises the following steps: step one, preparing a polydimethylsiloxane-epoxy diblock copolymer; step two, preparing a halogen atom terminated polydimethylsiloxane chain initiator; step three, preparing a polydimethylsiloxane-epoxy-b-polystyrene triblock copolymer; step four, preparing a polydimethylsiloxane-epoxy-b-polystyrene-b-hexafluorobutyl polymethacrylate tetrablock polymer. Epoxy chain segments introduced in the reaction have high adhesion, so that the adhesion to the target substrate surfaces is greatly improved, and the firm adhesion to various substrate surfaces can be achieved.
