2-Hydroxyethyl methacrylate (HEMA) is perhaps the most widely studied and
used neutral hydrophilic monomer . The monomer is soluble, its homopolymer
is water-insoluble but plasticized and swollen in water . This monomer is the
basis for many hydrogel products such as soft contact lenses, as well as polymer
binders for controlled drug release, absorbants for body fluids and lubricious
coatings . As a comonomer with other ester monomers, HEMA can be used to
control hydrophobicity or introduce reactive sites .

Difunctional molecule reactive in vinyl polymerization through its allylic
group, to impart hydrophilic properties to aqueous solution or emulsion
polymers . In particular, solution copolymers of Hydroxypolyethoxy (10)
Allyl Ether with Acrylic acid have shown useful properties as dispersants and scale inhibitors
in boiler water applications .Hydroxypolyethoxy (10) Allyl Ether is a high purity material, clear,
slightly viscous liquid (5 cps at 20°C) which undergoes partial solidification below 10° C to form
a viscous paste .
