Adhesive sheet and preparation method thereof

ActiveCN104449452AImprove liquidityDegassing process parameters require looseFilm/foil adhesivesLaminationPolyesterPolymer science
The invention discloses an adhesive sheet and a preparation method thereof. The adhesive sheet comprises an ABA-structural adhesive resin layer, a light-release-type polyester film layer and a heavy-release-type polyester film layer, wherein the light-release-type polyester film layer is arranged on the ABA-structural adhesive resin layer and the heavy-release-type polyester film layer is arranged under the BA-structural adhesive resin layer. The adhesive sheet is characterized in that the ABA-structural adhesive resin layer comprises adhesive layers A as upper and lower layers and a support layer B as an intermediate layer, each of the adhesive layers A comprises a solvent-based polyacrylate copolymer adhesive resin, a monomer containing unsaturated bonds and a UV initiator and the support layer B comprises the solvent-based polyacrylate copolymer adhesive resin and a crosslinking curing agent. The adhesive layers and the support layer are completely made of solvent-based thermosetting materials, after the adhesive sheet and a laminate are adhered, degassed by virtue of an autoclave and the rear section is fixed and cured by UV radiation so that the problem that bubbles remain in a border caused by the cold contraction of a colloid can be completely avoided; the yield rate of the product is high, the preparation process is simple and the coating process can be specifically selected according to a device.

Styrene derivative-methacrylate copolymer containing photo-acid generation groups as well as preparation and application of styrene derivative-methacrylate copolymer

The invention provides a styrene derivative-methacrylate multipolymer containing photo-acid generation groups, a synthetic method of the multipolymer and an application of the multipolymer to a photoresist material. The multipolymer is prepared from p-styrenesulfonate, 4-ethenylphenol acetate and methacrylate through a free radical polymerization reaction, an acetoxyl group is converted into a hydroxyl group with an acid catalysis deprotection method, the polymer has an ion exchange reaction with onium salt halide, and the styrene derivative-methacrylate copolymer containing the photo-acid generation groups is obtained. The polymer contains the photo-acid generation groups and produces macromolecular sulfonic acid in an exposure process, so that the polymer can be taken as a macromolecular photo-acid generator used by the chemical amplification type photoresist; besides, part of phenolic hydroxyl groups in the polymer can be protected by acidolysis groups, and the polymer can be used as the photo-acid generator and can be also used for preparing a single-component 248-nm photoresist material. The polymer can be applied to a resist applied to photoetching techniques of deep ultraviolet, extreme ultraviolet, electron beams and the like.
