    Abstract: A liquid crystal alignment agent containing at least two kinds of polymers selected from the group consisting of polyamic acids and imidized polymers and having a structure obtained by dehydration and ring closure of polyamic acid. In the at least two kinds of polymers contained in the liquid crystal alignment agent, the polymer of higher imidization degree has a smaller surface free energy. The liquid crystal alignment agent gives a liquid crystal display device having less stuck image and high pretilt angle.

    Abstract: Disclosed is a thermoplastic elastomer composition obtained by dynamically heat-treating a mixture containing a thermoplastic resin (A) having a melting point of not less than 200˚C and an elastomer (B) having a constitutional unit derived from an ester group-containing monomer in the presence of a polymer (C-1) which is composed only of a (meth)acrylate unit (c-1) and has a weight average molecular weight Mw of 1,000-30,000 and a molecular weight distribution Mw/Mn of 1.0-4.0 and/or a polymer (C-2) which is composed of 5-35 mass% of a (meth)acrylate unit (c-1) and 65-95 mass% of an aromatic vinyl monomer unit (c-2) and has a weight average molecular weight Mw of 1,000-30,000 and a molecular weight distribution Mw/Mn of 1.0-4.0, as a crosslinking agent (C). Such a thermoplastic elastomer composition has a good sea-island structure as a whole and is excellent in cold resistance. Consequently, the thermoplastic elastomer composition is useful as an alternative to acrylic rubbers.
