Properties: Liquid. Mild, sweet odor resembling that of chloroform. d420 1.2129. mp -122.5°. bp760 31.7°. nD20 1.4249. Practically insol in water. Sol in organic solvents. At temps 0° and especially in the presence of oxygen or other suitable catalysts polymerizes to a plastic. Several inhibitors to preserve the monomer have been invented. Uncontrolled polymerization may lead to explosive reaction products with oxygen or ozone: Reinhardt, Chem. Eng. News
