摘要： This invention provides certain carboxymethyl cellulose (CMC) esters of higher acids (e.g., CMC acetate propionate, CMC propionate, CMC acetate butyrate, and CMC butyrate). These new ether derivatives of cellulose esters exhibit solubility in a wide range of organic solvents, compatibility with a variety of resins, and ease of dispersion in a water-borne formulation and are useful in coating compositions as binder resins and rheology modifiers.

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. 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.

摘要： This invention pertains, firstly, to the use of mixtures of hydriodic acid and organic solvent soluble iodide salts as catalysts for the hydration of .gamma.,.delta.-epoxyalkenes to form a mixture of the corresponding 2-alkene-1,4-diol and 3-alkene-1,2-diol isomers. Secondly, this invention describes the use of pH to control the 2-alkene-1,4-diol/3-alkene-1,2-diol product ratio, and achieve improved 2-alkene-1,4-diol selectivities by controlling the pH to near neutral values. Thirdly, this invention includes a catalyst recovery process whereby a liquid/liquid extraction is used to separate the product from the catalyst. In this extraction, .gamma.,.delta.-epoxyalkene, or a .gamma.,.delta.-epoxyalkene-containing organic solvent, is used to extract the catalysts from water, leaving the diol products in the aqueous phase, from which they may be subsequently recovered by distillation, extraction or by other means.
