Neutral route - various amines, triblock copolymers, and alkyl-ethylene oxides are used for preparation of different hexagonal mesoporous sieves, SBA-15, SBA-16, or OMAs. 

Within the scope of the original definition, a very wide variety of ionomers can be obtained by the introduction of acidic groups at molar concentrations below 10% into the important addition polymer families, followed by partial neutralization with metal cations or amines. Extensive studies have been reported, and useful reviews of the polymers have appeared (3—8). Despite the broad scope of the field and the unusual property combinations obtainable, commercial exploitation has been confined mainly to the original family based on ethylene copolymers. The reasons for this situation have been discussed (9). Within certain industries, such as flexible packaging, the word ionomer is understood to mean a copolymer of ethylene with methacrylic or acryhc acid, partly neutralized with sodium or zinc. 

Ethylene-acrylic acid copolymer neutralized with amines such as triethanol amine or N-methyl diethanol amine enhances anti-settling properties [1198, 1554].
