摘要： The present invention relates to cellulose esters having low hydroxyl content for use in optical applications, such as liquid crystal display (LCD) films. Films made with low hydroxyl levels and a given ratio of non-acetyl ester to hydroxyl level have been found to have low intrinsic birefringence. Therefore, these films can be cast, molded, or otherwise oriented without an appreciable birefringence or optical distortion (i.e. retardation). Such features make these films useful in polarizer, protective, and compensator films as well as molded optical parts, such as lenses. Furthermore, it has also been found that resins of the present invention can also be made to have +C plate behavior either by melt or solvent based processing, a characteristic which is not typical of cellulose esters. Such +C behavior allows films to be produced having unique compensatory behavior. Other embodiments of the invention relate to methods melt casting films while minimizing birefringence formation. Another embodiment of the invention is directed to films made from the cellulose esters described herein further comprising a plasticizer.

摘要： This invention relates to a polymer blend comprising: (A) about 1% by weight to about 99% by weight of at least one polymer (A) comprising terephthalic acid residues, 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues; and 1,4-cyclohexanedimethanol residues; (B) about 1% by weight to about 99% by weight of at least one polymer (B) comprising 1,4-cyclohexanedicarboxylic acid residues and 1,4-cyclohexanedimethanol residues, and (C) about 0.01% by weight to about 20% by weight of at least one antimicrobial agent; said weight percentages being based on the total weight of the polymer blend.

摘要： A UV-protected, laminated article obtained by a thermocompressive lamination process. The laminated article is characterized by reduced haze due to the use of a benzotriazine UV absorber. A process for making such a laminated article and a method for preventing or inhibiting haze from developing in a UV-protected laminated article during application of heat and pressure are also described.
