The present invention relates to processes utilizing ionic liquids for the dissolution of various polymers and/or copolymers, the formation of resins and blends, and the reconstitution of polymer and/or copolymer solutions, and the dissolution and blending of 'functional additives' and/or various polymers and/or copolymers to form advanced composite materials.

Polymer dissolution and blend formation in ionic liquids

Cellulose is dissolved in an ionic liquid without derivatization, and is regenerated in a range of structural forms without requiring the use of harmful or volatile organic solvents. Cellulose solubility and the solution properties can be controlled by the selection of the ionic liquid constituents, with small cations and halide or pseudohalide anions favoring solution.

Dissolution and processing of cellulose using ionic liquids

A regenerated cellulose-encapsulated active substance and a method for encapsulating an active substance in a regenerated cellulose matrix are disclosed. The distribution of the active substance is preferably substantially homogeneous within the matrix of regenerated cellulose. The regenerated cellulose (i) has about the same molecular weight as the original cellulose from which it is prepared (ii) is substantially free of added substituent groups relative to the starting cellulose and is also substantially free of entrapped ionic liquid degradation products.

Cellulose matrix encapsulation and method

A temperature sensor having a capillary tube or stem, sealed at both ends, with a thin bore defined therein is applied to the measurement of temperatures having a range of about &minus;100&deg; to &plus;400&deg; Centigrade. A bulb comprising a liquid reservoir, is provided at one end of the capillary tube, in liquid communication with the bore, and is generally filled with an ionic thermometric liquid. In the operation of the temperature sensor, temperature is measured by the height of the liquid in the bore.
