2. Chain extender - Wikipedia

   en.wikipedia.org/wiki/Chain_extender

   At or near the final stages of production, the material is treated with a chain extender. Typically, chain extenders are bifunctional, i.e., they have two functional groups, which can link together two polymers. Representative classes of chain extenders are diglycidyl ethers, diols, diamines, or dianhydrides. Chain extenders are often applied ...

3. Dealkalization of water - Wikipedia

   en.wikipedia.org/wiki/Dealkalization_of_water

   Chloride cycle dealkalizers operate similar to sodium cycle cation water softeners. Like water softeners, dealkalizers contain ion-exchange resins that are regenerated with a concentrated salt solution - NaCl. In the case of a water softener, the cation exchange resin is exchanging sodium (the Na + ion of NaCl) for hardness minerals such as ...

7. 1,6-Hexanediol - Wikipedia

   en.wikipedia.org/wiki/1,6-hexanediol

   1,6-Hexanediol can improve the hardness and flexibility of polyesters as it contains a fairly long hydrocarbon chain. In polyurethanes, it is used as a chain extender , and the resulting modified polyurethane has high resistance to hydrolysis as well as mechanical strength, but with a low glass transition temperature.
