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 formula:hoch2ch2o(ch2ch2o)nh.Poly(ethylene oxide) is water soluble resins.Aqueous solutions with low concentrations are very tacky and sticky. Poly(ethylene oxide) can used as long fibre dispersing agent in manufacture of paper, adhesives, friction reduction agent, flocculating agents, thickecing agents and lubricants and so on.
