Polyoxyalkylene ether polyols, hereinafter for convenience called polyols, are commonly used in the production of urethane polymers. These polyols are reacted with polyisocyanate in the presence of added catalyst and other materials to produce urethane ...
Specific gravity is 2.534, melting point of 880¡æ. It is dissolvable in water and acid but not dissolvable in alcohol and ammonia. Its aqueous solution, which is of alkalinity, when boiled, will be hydrolyzed to Na2HPO4. White powder or lumps.
Poly(Ethylene Oxide) 1.USAGE: Poly(ethylene oxide) resins are high molecular weight homoploymers produced by the heterogeneous catalytic polymerisation of ethylene oxide.The resins are characterised by the structural ...
