Polymeric treatment compositions

A method of treating a vascular condition comprising:

• guiding a delivery device to an area in need of treatment within a physiological environment;
• injecting through the delivery device into the physiological environment a liquid embolic composition comprising a biocompatible polymer including a first monomer selected from a group consisting of aminopropyl methacrylamide, aminoethyl methacrylamide, aminoethyl methacylate, aminopropyl methacylate, N-(3-methylpyridine)acrylamide, N-(2-(4-aminophenyl)ethylacrylamide, N-(4-aminobenzyl)acrylamide, N-(2-4-imidazolyl)ethyl)acrylamide, and combinations thereof, a second monomer including an acrylate, acrylamide, a derivative thereof, or a combination thereof, an aqueous solution, and a visualization agent, wherein the visualization agent is an iodinated compound, barium sulfate tantalum, superparamagnetic iron oxide, gadolinium molecules, or a combination thereof, wherein the biocompatible polymer is soluble in the aqueous solution and insoluble in the physiological environment thereby immediately precipitating and forming a solid polymeric mass at the area in need of treatment;
• and
• treating the vascular condition.
