For acrylic nails..........?

what is the difference between acetone and monomer to use with the acrylic powder?For acrylic nails..........?
Alrighty a bit of polymer chemistry for ya.





Acetone is a ketone and is two methyl groups flanking a central carbonyl group; it is an organic solvent and is not a polymer, nor can it be made into one.





The PMMA or polyethylmethylmethacrylate (powder) is a polymer powder which means ';many'; So these compound have a lot of links in their chains. The links here are ethymethylmethacrylate and they are connected in chains, ';poly'; chains over various lengths. Like polyethylene glycol. It is ethylene glycol linked over and over in various lengths. The longer the length the more rigid the PEG.





The monomer, is a liquid of a single headed polymer. When the monomer and powder polymer come together, cross linking occurs between the original PMMA crystals via the monomer solution and it makes it into a gel which is then shaped. Once the gel is shaped it is dried and becomes very hard and durable due to the crosslinking of the bonds between the polymer chains. Crosslinking causes the bonds to form a net like structure between the molecules.
