A liquid crystal polyester wherein a linear liquid crystal polymer chain including specific monomers (A) to (C), in which at least one of the monomer (B) and the monomer (C) contains a compound for forming a bent structural unit, and a content of the compound for forming a bent structural unit is 20 to 40% by mol relative to a total molar amount of the monomers (A) to (C), is bonded via a specific monomer (D), and a content proportion of the monomer (D) is 0.01 to 10 mol relative to 100 mol of the total molar amount of the monomers (A) to (C).

The present application discloses a bending-resistant polyester film and its production method thereof. The chemical structure of the bending-resistant polyester composition comprises monomers having elastic conformation. The film made from the composition of polyester of the present invention through production processes such as melt extrusion and biaxial drawing still has excellent flexibility and optical properties.

Polymers are disclosed that incorporate portions of secondary or tertiary polyamide segments connected with polyisocyanates. These polymers have enhanced matting properties. The enhanced matting properties are from creating an inherently matt surface from the polymer without the use of any separate fine particle size matting additives. Conventional matting agents such as fine particle size silica usually results in loss of physical properties such as haze development and porosity in the coating from the matting agent. Composites and hybrids of these polymers and other polyamides, polyurethane with vinyl polymers (acrylates) are also disclosed and claimed.

The present application is directed to methods for solvent-free preparation of polymers and their subsequent processing into activated carbon materials. These methods unexpectedly demonstrate ability to tune pore structure in the polymer gel and carbon produced there from, while also providing distinct advantages over the current art.

Linear, comb, and star shaped non-ionic polyesters and copolyesters, polyesteramides, polyamides, and copolyamides may be synthesized from the condensation polymerization of polyacids containing alpha-hydroxy polyacids and diols and/or polyols, and amino-diols and/or amines using boric acid, boric anhydride, and boronic acids as catalysts. Depending on the polyol, polyamine, and amino alcohol component, the resulting compound may be hydrophilic or hydrophobic, but not water soluble or dispersible, enabling use in packaging films, fibers, and other molded articles. The compounds may be completely water soluble, water dispersible, and/or amphipathic, thus being useful in cosmetics, agricultural compositions, biomedical and pharmaceutical applications.
