Cellulose plastics ethers

Cellulosic plastics Group of plastics composed of cellulose compounds for example, esters (e.g., cellulose acetate) and ethers (e.g., ethyl cellulose).

Due to infusibility and insolubility of cellulose, it is usually converted into derivatives to make it more processable. Some important derivatives of cellulose include ethers like methyl cellulose and hydroxyl-ethyl cellulose, and esters such as cellulose acetate, cellulose butyrate, cellulose acetate-butyrate, etc. However, little attention has been given to these materials in efforts to develop biodegradable plastics. Slow degradation rates, high cost, and processes that generate some noxious discharges are the likely reasons [10, 12]. 

Benzyl cellulose n. A benzyl ether of cellulose, it is a cellulosic plastic used in lacquers. It also may be formulated for making films and compounds for molding and extrusion.

Cellulosic plastics plastics based on modified cellulose (organic fibre). Divided into mainly cellulose esters and cellulose ethers. 

Occasionally, water-soluble plastics are required. Poly(vinyl alcohol) is commonly the first to be considered but some cellulose ethers, polyethylene oxides, poly(vinyl pyrrolidone) and A-substituted polyamides are among many possible alternatives. 

Cellulose ethers of a high degree of substitution are stable, relatively nonflammable, resistant to ultra-violet light and compatible with a wide range of solvents and plasticizers. Certain ethers of a low degree of substitution are soluble in water or alkali. It would appear from these properties that cellulose ethers should be ideally adapted for use in the plastics field and for many other uses.

Ethylhydroxyethylcellulose (EHEC) is a nonionic mixed ether available in a wide variety of substitutions with corresponding variations in aqueous and organic liquid solubilities. It is compatible with many oils, resins, and plasticizers along with other polymers such as nitrocellulose. EHEC is synthesized through a two-step process beginning with the formation of the HEC-like product through reaction between the basic cellulose and ethylene oxide. The second step involves further reaction with ethyl chloride.
