Manufacturing method of vinylphthalic acid and vinylphthalic acid for manufacturing aminocarbonylstyrene

The present invention relates to a method for preparing a vinylphthalic acid. More specifically, the present invention can prepare a high yield of the vinylphthalic acid through a short preparation process with high productivity. The method enables the vinylphthalic acid to be mass-produced and be used as an intermediate to enable the mass production of (aminocarbonyl)styrene compounds and amide side-chain liquid crystalline polymers.COPYRIGHT KIPO 2015

Manufacturing method of vinylphthalate and vinylphthalate for manufacturing aminocarbonylstyrene

The present invention relates to a method for producing vinylphthalate whereby, more specifically, vinyl phthalate can be produced with not only high productivity but also high yield by a short production process. By the method, mass production of vinylphthalate can be possible. When vinylphthalate is used as an intermediate, mass production of an aminocarbonyl styrene compound and an amide side-chain liquid crystalline polymer can be possible.COPYRIGHT KIPO 2015

Influences of hydrogen bonding and peripheral chain length on mesophase structures of mesogen-jacketed liquid crystalline polymers with amide side-chain linkages

A series of mesogen-jacketed liquid crystalline polymers, poly{2,5-bis[(4-alkoxyphenyl)aminocarbonyl]styrene} (P-Cm, where m is the number of carbon atoms in the alkoxy groups, and m = 1, 4, 8, 12), with an amide core and flexible tails of varying lengths on the two ends in the side chain were designed and successfully synthesized via conventional radical polymerization. The mesophase structures of these polymers were dependent on the number of carbon atoms in the peripheral chains. Wide-angle X-ray diffraction and polarized light microscopy results revealed that the polymers with m ≥ 4 could form smectic A phases, while a columnar nematic phase could be formed for the polymer with methoxy end groups (P-C1). The hydrogen bonding among the side-chain amide groups might play an important role in forming and stabilizing these liquid crystalline phases, which was suggested by the results from variable-temperature FTIR and 2D IR analyses.
