Dodecylmethacrylate

Other viscosifiers described in the literature include acrylate copolymers such as poly(acrylamide-co-dodecylmethacrylate)... 

DODECYLMETHACRYLATE (142-90-5) Combustible liquid (flash point >230°F/ >110°C). Unless inhibited (90—120 ppm hydroquinone recommended), able to form unstable peroxides. Strong oxidizers or reducing agents may cause polymerization, fires, or explosion. 

In the case of monomers with low water solubility, another problem arises. In emulsion polymerizations, transport of monomer from monomer droplets to the growing polymer particles is needed, which demands a minimum water solubility of the monomer. For example dodecylmethacrylate (water solubility of 0.065 mmol/L) cannot be polymerized by conventional emulsion polymerization. Another reason for hydrophobic monomers to polymerize slowly in emulsion polymerization could be that entry of radicals is slow because the oligomers do not grow to their critical chain length [32]. Another solution to this problem is to directly polymerize within the monomer droplets, which have to be very small in order to keep the benefits of producing polymer in the form of latex. In contrast to emulsion polymerization, where the droplets are of the same size as those in suspension polymerization (10-100pm), in mini- and microemulsion polymerization the droplets are very much smaller and enable the polymerization to take place directly within the monomer droplets.
