[0065] According to one embodiment of the present specification, the step (s32) (drying step) is performed by adding a drying agent to any one of the layers of the substances separated in the step (s31).

[0069] According to one embodiment of the present specification, an additional filtration and drying step may be added after the step (s34).
[0070] Before the step of obtaining (s35), a drying step may be included, and the drying step is a step of drying the chemical formula 1. Different from (s32), the drying step may be performed by a method known in the art. Typical examples include vacuum oven drying, spray drying, flash drying, etc., and preferably, it may be dried by vacuum oven drying.

[0073] According to one embodiment of the present specification, a mixture containing two or more kinds of the compounds is provided.
[0074] According to another embodiment of the present specification, two or more compounds contained in the mixture may be the same as or different from each other. That is, it means having the structure of Chemical Formula 1 and being the same as or different from each other.
[0075] According to another embodiment of the present specification, the mixture may further contain a compound different from Chemical Formula 1.
[0076] According to one embodiment of the present specification, a single molecule derived from the compound is provided.
[0077] In the present specification, for example, the "single molecule derived from the compound of Chemical Formula 1" may mean a molecule in which a vinyl group of the compound of Chemical Formula 1 forms a radical and an additional substituent is introduced, or the compound of Chemical Formula 1 itself.
[0078] According to one embodiment of the present specification, a polymer containing a monomer derived from the compound is provided.
[0079] Those having ordinary knowledge in the art can understand that the term "monomer" described in the present specification refers to a state in which a compound polymerizes and is linked to the main chain of a polymer.
[0080] In the present specification, for example, the "monomer derived from the compound of Chemical Formula 1" means that as a repeating unit constituting the main chain in a polymer, a vinyl group of the compound of Chemical Formula 1 can form a radical to become a monomer, and monomers or end groups constituting the main chain of other polymers can be introduced.
[0081] According to one embodiment of the present specification, the polymer may further contain an additional monomer, and the additional monomer is not limited.
[0082] According to one embodiment of the present specification, the polymer may be an alternating polymer or a random polymer, but is not limited thereto.
[0083] Also, in this specification, when referring to the monomers contained in the polymer, it is not limited to containing only the monomers mentioned, and within the scope not departing from the object of the present invention, in addition to the monomers mentioned above, other monomers may be further included as comonomers.
[0084] According to one embodiment of this specification, a resin composition containing the compound, the monomer and polymer derived therefrom is provided.
[0085] The compound, the monomer and polymer derived therefrom according to one embodiment of this specification are used as electronic materials, organic insulating materials, and / or substrate materials, and are not limited thereto.
[0086] The compound, the monomer and polymer derived therefrom according to one embodiment of this specification can be used as a semiconductor CCL (Copper Clad Laminate) material. Specifically, typical materials used for semiconductor CCL materials include a plurality of monomers and polymers having a styrene group, monomers and polymers having a bismaleimide group, and the like.
[0087] The bismaleimide group is similar in structure to maleic anhydride. In fact, it is generally known that the styrene group forms an alternating copolymer very effectively with the bismaleimide group and the maleimide group during polymerization. This is because the transition state of the non-bonded resonance form including electron transfer is stabilized by the polar effect charge transfer interaction.
[0088] Therefore, the compound of Chemical Formula 1 containing a perfluoroalkyl group having non-dielectric rate characteristics is expected to be able to more effectively induce a thermoset network generated during curing than conventional compounds. As a result, without the need for additional new additives, the dielectric rate of a conventional insulating layer can be effectively reduced without phase separation from conventional substances.

Then, at 30 °C, nitrogen was bubbled through the solution for 30 minutes. To this solution, 0.37 g of V-70 (2,2'-azobis(4-methoxy-2,4-dimethylvaleronitrile)) was added, and the mixture was stirred for 15 hours.
