MULTIFUNCTIONAL PLASTIC ... POLY(ETHYLENE OXIDE)
1. What is ALKOX® Resins?
ALKOX® Resins are high molecular weight poly(ethylene oxide) with the following poly ether structure, and they are produced from ethylene oxide by a ring-opening polymerization process, using our originally prepared organo metallic catalysts. Their molecular weights range from 100,000 to 8 million.
∼(O-CH2-CH2)n∼
ALKOX® Resins are supplied as white, granular powders with the melting point 65-67ºC, and can be molded to make a hard and elastic plate because of their thermoplastic property.
On the other hand, they are completely soluble in water, and because of the high viscosity of their aqueous solutions they have been applied in various fields.
Thus the co-existence of thermoplastic and water-soluble nature is the fundamental characteristic of ALKOX® resins and, therefore, wide variety of final uses, different from other resins, are expected to be developed
2. Characteristics and Versatility of ALKOX® Resin as Industrial High Polymer Materials
| Aqueous ALKOX® Solutions |
|
- ALKOX® resins are completely soluble in water.
- Lean agueous solution of ALKOX® reduce hydrodynamic drag remarkably.
- Show high viscosity and strong stringiness at even very low concentration.
- Coagulate and sediment suspension of clay, silica, fine fiber and others.
- When wet, ALKOX® resins show high adhesive effect and when dried, they can be easily removed.
|
| ALKOX® Resin |
|
- ALKOX® resins are soluble in many kinds of polar organic solvents.
- Moisture absorption at usual relative humidity is less.
- ALKOX® resins are compatible with many other resins and plastics.
- ALKOX® resins can be shaped by roll press, injection or molding.
- ALKOX® resins form usual polymer electrolytes, when mixed with many inorganic salts and organic acids.
|
| Toxicological Properties |
|
- ALKOX® resins are completely combustible, when burned, and produce no toxic gases.
- ALKOX® resins process a very low degree of oral toxicity.
- ALKOX® resins are almost non-irritative to the human skin and eyes.
- ALKOX® resins cause almost no pollution problem in the plant effluent due to the very low biological oxygen demand.
