    摘要: An object of the present invention is to provide a polymerizable liquid crystal composition incorporating a polymerizable liquid crystal compound which displays a low nematic phase temperature, displays excellent compatibility with other polymerizable liquid crystal compounds, and furthermore yields a product following polymerization, of good transparency and high mechanical strength.
    A polymerizable composition is provided which displays a liquid crystal phase, and moreover incorporates a liquid crystal backbone with two or more ring structures and a compound with a partial structure represented by the general formula P 1 -S 1 -A 1 -D 1 -E 1 - [wherein P 1 represents a polymerizable functional group; S 1 represents -(CH 2 ) w -, - O(CH 2 ) w -, -(CH 2 ) w O-, -(CH 2 ) w C(=O)O-, -(CH 2 ) w OC(=O)-, -C(=O)O(CH 2 ) w - or - OC(=O)(CH 2 ) w - (w: 1 to 20); A 1 and E 1 each represent a hydrocarbon ring or a hetero ring, although E 1 is a ring incorporated within the liquid crystal backbone; and D 1 represents - C(=O)-O-(CH 2 ) m -O-, -O(CH 2 ) m -O-C(=O)-, -O-C(=O)-(CH 2 ) m -O-, or -O(CH 2 ) m -C(=O)-O- (m: 1 to 15)].

    摘要: Provided is a fluorine-based surfactant including a copolymer synthesized by copolymerizing, as essential monomers, a polymerizable monomer (A) having a poly(perfluoroalkylene ether) chain and polymerizable unsaturated groups at both ends of the chain and a polymerizable monomer (B) having an oxyalkylene group and a polymerizable unsaturated group. The fluorine-based surfactant cannot structurally generate PFOS or PFOA, which tend to accumulate in the environment and living bodies; even when the fluorine-based surfactant has lower fluorine content than surfactants having a fluoroalkyl group having 8 or more carbon atoms, the fluorine-based surfactant has a higher capability of decreasing surface tension than the surfactants. Accordingly, the fluorine-based surfactant can be suitably used as a leveling agent for a coating composition, a resist composition, or the like.
