摘要： Novel poly(3-hydroxyalkanoates), such as poly(3-hydroxybutyrate), and blends of these with other polymers are disclosed. A novel process for producing these poly(3-hydroxyalkanoates) is also disclosed which entails polymerizing one or more β-substituted-β-propiolactone(s) under polymerization conditions in the substantial absence of water in the presence of an anionic initiator.

摘要： Ionic liquids and cellulose ester compositions and processes for producing ionic liquids and cellulose esters. Cellulose esters can be produced by subjecting a cellulose-ionic liquid solution comprising cellulose, one or more ionic liquids, and one or more co-solvents to esterification to thereby produce an esterified medium comprising a cellulose ester. The cosolvents employed in the present invention can be either miscible or immiscible with the cellulose-ionic liquid solution but can be readily dispersed or soluble in the esterified medium.

摘要： Ionic liquids and cellulose ester compositions and processes and apparatus for producing ionic liquids and cellulose esters. Cellulose esters can be produced by dissolving cellulose in carboxylated ionic liquids and thereafter contacting the cellulose solution with at least one acylating reagent. Cellulose esters produced via the present invention can comprise ester groups that originate from the carboxylated ionic liquid and/or the acylating reagent.

摘要： The present invention relates to a multilayer cellulose ester film having a reversed optical dispersion. The film can have an A-B bi-layer or an A-B-A tri-layer configuration. The cellulose ester material for layer A has a hydroxyl degree of substitution (DSOH) from 0 to 0.5, while the cellulose ester material for layer B has a DSOH from 0.5 to 1.3. By manipulating the thickness of layers A and B, and the film stretching conditions, desirable optical retardation and optical dispersion properties can be obtained. The film can be used as an optical waveplate in liquid crystal displays to improve viewing angle, contrast ratio, and color shift.
