The monomer can be categorized into three classes. The first two classes are characterized by their respective Tg values. Soft monomers, characterized by low Tg values, include n-butyl acrylate, 2-ethyl hexyl acrylate and iso-octyl acrylate. These monomers are longer chain alkyl acrylates and exhibit low water solubility (i.e., high hydrophobicity). Hard monomers, characterized by high Tg values, include styrene, methyl methacrylate, ethyl acrylate and methyl acrylate. The third class is the functional monomer with various functional groups, such as carboxyl or hydroxyl. Examples of functional monomers are acrylic acid and hydroxyethyl acrylate,which are very water-soluble. The hydrophobicity of the hard monomer depends on the monomer structure. Methyl acrylate and ethyl acrylate, which are short-chain alkyl acrylates, have higher water solubility.

What are the monomers in spandex?
Spandex polymers are composed of three different monomers. Dialcohol monomers make up the rubbery, soft part of the polymer while diamine and diisocyanate monomers make up the rigid, hard part of the polymer. The three monomers of spandex therefore are dialcohol, diamine and diisocyanate.
