There are two alkyl chains commonly used in surfactants : polyethylene oxide and polypropylene oxide.
2.
Polyethylene oxide, or high-molecular weight polyethylene glycol, is synthesized by suspension polymerization.
3.
The polyether groups often comprise ethoxylated ( polyethylene oxide-like ) sequences inserted to increase the hydrophilic character of a surfactant.
4.
Formation aid is polyethylene oxide, and it helps slow the flow of water, which gives the paper-maker more time to form sheets.
5.
The base resin is polystyrene onto which is attached long chains ( MW ca . 3000 Da ) of polyethylene glycol ( PEG; also known as polyethylene oxide ).
6.
Polyethylene oxide chains have an oxygen and two carbon (-O-CH 2-CH 2-) n repeating unit and has an increased hydrophilic character compared to hydrocarbons.
7.
Polypropylene oxide has the same backbone structure as polyethylene oxide but with a methyl group substituent of one of the carbons, and this structure has hydrophobicity between hydrocarbons and polyethylene oxides.

Polypropylene oxide has the same backbone structure as polyethylene oxide but with a methyl group substituent of one of the carbons, and this structure has hydrophobicity between hydrocarbons and polyethylene oxides.
9.
By combining salts and polyethers such as polyethylene oxide (-CH 2-CH 2-O-) n, it is possible to synthesise thousands of metal-polyether complexes, alternatively known as polymer electrolytes.
10.
Other materials are also used to make a superabsorbent polymer, such as polyacrylamide copolymer, ethylene maleic anhydride copolymer, cross-linked carboxymethylcellulose, polyvinyl alcohol copolymers, cross-linked polyethylene oxide, and starch grafted copolymer of polyacrylonitrile to name a few.
