摘要:
Disclosed herein is a novel functional diamine compound having a dendron structure, polyamic acid which is produced using functional diamine, aromatic cyclic diamine, aliphatic cyclic acid dianhydride, and aromatic cyclic acid dianhydride, polyimide which is produced by imidizing polyamic acid, and an LC alignment film produced using polyimide. Even if the diamine compound is used in a small amount, it is possible to realize a high pretilt angle, thus the pretilt angle is easily controlled. Therefore, it can be used to produce an LC alignment film using a twisted nematic (TN) mode, in which the pretilt angle of liquid crystal is low, and a vertically aligned (VA) mode, which requires a high pretilt angle of about 90°.

Disclosed herein are a novel diamine compound having a dendron side chain and a liquid crystal alignment material produced using the diamine compound. Specifically, the diamine compound is used to prepare a polyamic acid, which is then used to produce the liquid crystal alignment material. According to the liquid crystal alignment material, the pretilt angle of a liquid crystal is easy to control, and the alignment properties of a liquid crystal are good. Particularly, since the liquid crystal alignment material shows superior chemical resistance to washing solvents used in LCD panel fabrication processes, it has an advantage in that the alignment properties of a liquid crystal are not degraded even after washing.

A matte thermoplastic resin composition consisting essentially of:(A) 70-97% by weight of a rubber-modified alkenyl a romatic thermoplastic resin and(B) 30-3% by weight of a graft copolymer as a high polymer modifier for matting, obtained by polymerizting an ethylenically unsaturated carboxylic acid and at least one monomer selected from the group consisting of an alkenyl aromatic compound, an alkenyl cyanide compound and other copolymerizable alkenyl monomer in the presence of a rubbery polymer latex, wherein the content of the ethylenically unsaturated carboxylic acid component in the graft copolymer (B) is 1-30% by weight and the content of the rubbery polymer in the graft copolymer (B) is 10-60% by weight. Said composition has an excellent matte effect especially when the rubbery polymer latex gives a percentage coagulation of 20% by weight or less based on the total solids of the latex when 15% by weight, based on the total solids, of methacrylic acid is added to the latex.
