Description

【0001】
【発明の属する技術分野】
本発明は、新規なポリフルオロアルキル基含有重合性化合物およびその重合体に関する。
【0002】
【従来の技術】
ポリフルオロアルキル基(以下、R基と記す。)が環状炭化水素基に直接結合した構造を有する重合性化合物としては、トリフルオロメチル基がベンゼン環に直接結合した構造を有する重合性化合物が知られているが、該化合物を重合して得られた重合体は、4−トリフルオロメチル基が配向しないため撥水撥油性が発現しない。また、R基を有する(メタ)アクリレートの重合体は、撥水撥油剤として広く利用されているが、炭素数6以下のR基では撥油性が充分に発現しない。
【0003】
【発明が解決しようとする課題】
本発明は、炭素数2以上のR基が環状炭化水素基に直接結合した構造を有するR含有重合性化合物およびその重合体を提供することを目的とする。該化合物は、R基が環状炭化水素基に直接結合しているため、R基の配向を容易に制御できる。また、環状炭化水素基間の相互作用により、さらに容易にR基の配向を制御できる。また、炭素数2以上のR基が環状炭化水素基に直接結合することで、擬似メソゲン的効果が発現し、R基を高度に配向させることができる。そのため、炭素数の少ないR基でも優れた撥水撥油性が発現し、液晶性も発現することを見出した。
【0004】
【課題を解決するための手段】
本発明は、下式1で表されるR基含有重合性化合物(以下、化合物1とも記す。)および該重合性化合物を重合して得られた重合体を提供する。

BACKGROUND OF THE INVENTION
The present invention relates to a novel polyfluoroalkyl group-containing polymerizable compound and a polymer thereof.
[0002]
[Prior art]
Examples of the polymerizable compound having a structure in which a polyfluoroalkyl group (hereinafter referred to as R f group) is directly bonded to a cyclic hydrocarbon group include a polymerizable compound having a structure in which a trifluoromethyl group is directly bonded to a benzene ring. Although known, a polymer obtained by polymerizing the compound does not exhibit water and oil repellency because the 4-trifluoromethyl group is not oriented. In addition, a polymer of (meth) acrylate having an R f group is widely used as a water and oil repellent, but the oil repellency is not sufficiently exhibited with an R f group having 6 or less carbon atoms.
[0003]
[Problems to be solved by the invention]
An object of the present invention is to provide an R f -containing polymerizable compound having a structure in which an R f group having 2 or more carbon atoms is directly bonded to a cyclic hydrocarbon group, and a polymer thereof. In the compound, since the R f group is directly bonded to the cyclic hydrocarbon group, the orientation of the R f group can be easily controlled. Further, the orientation of the Rf group can be controlled more easily by the interaction between the cyclic hydrocarbon groups. Further, when the R f group having 2 or more carbon atoms is directly bonded to the cyclic hydrocarbon group, a pseudo mesogenic effect is exhibited and the R f group can be highly oriented. For this reason, it has been found that excellent water and oil repellency is exhibited even with an R f group having a small number of carbon atoms, and liquid crystallinity is also exhibited.
