Polymers

Description

Vinyl ethyl ether appears as a clear colorless low-boiling liquid (35-36°C) with an ether-like odor. Flash point below -50°F. May polymerize exothermically if heated or contaminated. If polymerization takes place inside a container, the container may rupture violently. Less dense than water and slightly soluble in water. Hence floats on water. Vapors are heavier than air.;Liquid;COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR.
