| titleOfInvention | Spirobenzopyran group-containing polymers, preparation methods thereof, and photochromic switch thin films using the same |
| abstract | The present invention provides a spiro benzopyran group-containing polymer prepared from a spiro benzopyran group-containing monomer having an unsaturated end group represented by the general formula (1) and an aliphatic and / or aromatic comonomer having an unsaturated functional group, a method for preparing the same, Gwangho using the same A modified thin film and a photochromic switch element. According to the present invention, a polymer having excellent mechanical properties and exhibiting fast photochromic switch characteristics at room temperature is provided, and a method of manufacturing a photochromic thin film of a switch element is provided, and these can be used in various areas of an article such as an optical switch using photochromic properties. It is also useful for use in photochromic filters, light stabilizers, anti-counterfeiting banknotes and cards, display elements, optical recording media, and optical integrated elements.n n n [Formula 1]n n n n n n n n [Wherein, R 1 represents a linear or branched alkyl or alkenyl group having 1 to 22 carbon atoms, or a phenyl or phenylalkyl group, wherein the alkyl, alkenyl and phenyl groups described above are halides such as hydroxy, fluoride, glycidone It may be substituted by functional groups, such as ci, amine, vinyl, epoxy, (meth) acryl, amino, or mercapto;n n n R 2 and R 3 each represent a hydrogen atom, a halogen atom, a cyano group, a substituted amino group, a nitro group, a substituted or straight chain or branched alkyl or alkoxy group having 1 to 10 carbon atoms;n n n R 4 is a substituted or alkylene or alkyleneoxy group having 1 to 22 carbon atoms and may include one or more heteroatoms selected from oxygen, sulfur, nitrogen, etc. in the carbon chain, and the aforementioned alkylene moiety is alkyl having 1 to 6 carbon atoms.
