Reactivity: Vinyl chloride polymerizes exothermically in the presence of light, air, oxygen or catalysts. Heat alone will not initiate polymerization. Vinyl chlo ride is theimally stable to quite high temperatures. Although peroxide formation due to air exposure is a slow reaction, certain peroxide products are shocksensitive. Vinyl chloride is noncorrosive to metals when dry at normal tempera tures, but water and elevated temperatures accelerate corrosion. "The double bond behaves as in other unsuturated compounds. The chlorine atom is relative ly inactive and is more stable than in saturated or allylic compounds.

HANDLING AND STORAGE j Aluminum and its alloys must not be / used in equipment to store or handle j vinyl chloride because explosive alumi num chloroalkyls can be formed. PPG's vinyl chloride is made from ethylene and contains no detectable amount of acety lene. Vinyl chloride made from acetylene by an older process contains traces of acetylene that could react explosively with copper or its alloys to form copper acetylides. It is not safe to use such vinyl chloride in processing equipment con taining copper or brass. Exposure of vinyl chloride to oxygen and air results, after a time, in polymer Carbon dioxide or dry chemical agents extinguish small fires effectively, but no extinguisher is known for large fires. Streams of water cannot extin guish a liquid vinyl chloride fire because the monomer does not mix with water and will float on top. Water may be sprayed to cool equipment. If the source of the vinyl chloride monomer leak has not been closed off, do not attempt to extinguish a large fire because hot metal can re-igmte an unburned vapor cloud. No one without proper protective respiratory equipment should enter an area where there has been a fire until the area has been adequately ventilated. Charles, Louisiana: Guayanilla, Puerto Rico; and Paulsboro, New Jersey. PPG maintains a fleet of tank cars for vinyl chloride service. All cars are equipped for top unloading. There are three car sizes: 100,000-pound. 180,000pound and 220,000-pound net weight. Tank trucks hold up to 40,000 pounds. Ships and barges hold up to several million pounds. SAMPLES AND SERVICE Samples of vinyl chloride are available on special request in returnable labora tory-size steel cylinders holding 5 pounds or in cylinders holding 200 pounds. The technical service staff of PPG In dustries Chemical Division is available for consulting on handling, storage and use. formation. This can cause problems in Unloading tank cars equipment used for storage and transfer of monomer. Vinyl chloride should be stored under a blanket of nitrogen with a i mmeaximum oxygen content of 10 ppm. ^7 If tank car valves are defective or ; Storage spheres at PPG s Lake Charles, Louisi leaky, do not unload.
