An inflatable lumbar support cushion for seats including a seat cushion assembly connected with an air bladder that has a hollow body and is covered by a lumbar support that is hollow. The air bladder is inflated by a pump unit assembly which includes a pump unit that blows air to the air bladder by an air hose adapting the size of the lumbar support as required and defining a lumbar support portion which provides comfort to a user. The air bladder configured as a cushion for a sofa. The pump unit can be electronic or manual. The seat cushion can be adapted to different seats by an attaching base located to a bottom surface thereof and the lumbar support may be attached to a backrest by a strap allowing to fasten the inflatable lumbar support cushion to any suitable seat.

Regioselectively substituted cellulose esters having a plurality of aryl-acyl substituents and a plurality of alkyl-acyl substituents are disclosed along with methods for making the same. Such cellulose esters may be suitable for use in optical films, such as optical films having certain Nz values, &#x2212;A optical films, and/or +C optical films. Optical films prepared employing such cellulose esters have a variety of commercial applications, such as, for example, as compensation films in liquid crystal displays and/or waveplates in creating circular polarized light used in 3-D technology.

This invention provides cellulose ester interpolymers, and methods of oxidizing cellulose interpolymers and cellulose ester interpolymers. The invention also provides routes to access carboxylated cellulose ester derivatives with high acid numbers wherein the carboxyl group is attached directly to the cellulose backbone by a carbon-carbon bond. Through functionalization of an intermediate aldehyde, the corresponding cationic or zwitterionic cellulose ester derivatives can also be accessed. The interpolymers of the present invention have a number of end-use applications, for example, as binder resins in various types of coating compositions and as drug delivery agents.

Cellulose interpolymers and method of oxidation

Ionic liquids and cellulose ester compositions and processes for producing ionic liquids and cellulose esters. Cellulose esters can be produced by esterifying cellulose in a reaction medium comprising one or more ionic liquids. Cellulose esters prepared via the methods of the present invention can be contacted with at least one bleaching agent to produce bleached cellulose esters having a &#x394;E value of less than 30.
