From chlorinated monomers and polymers

CO were estimated at 126 and 63 p.p.m., respectively [1178]. The quantity of phosgene formed from the thermal decomposition of 1 g of CHj=CHCl in a CH,=CHCl-air mixture between 100 and 1000 C is illustrated in Table 3.9 [1178] phosgene generation would therefore not be an important factor in a road tanker fire [ICI38]. 

Photo-oxidation of CHj=CHCI in air by u.v. irradiation, and in the presence of NOj, did not result in the formation of phosgene [725]. 

When pure 1,1-dichloroethene (vinylidene chloride) is exposed to oxygen, it develops a sharp odour as a result of the formation of a peroxide, which decomposes to phosgene and formaldehyde [1360a]. The peroxide precursor has been formulated as having either a cyclic or a polymeric structure  

Many hazardous materials may be produced during the burning of plastics in fires, incinerators, etc., and it is necessary to determine the risk, to fire fighters in particular. 

In view of the fact that poly(vinyl chloride) is frequently used in copper conduit, and that carbonaceous material is invariably formed during the combustion of plastics, then the co-combustion of poly(vinyl chloride), carbon and copper must constitute a commonly occurring situation. The thermal decomposition of poly( vinyl chloride) (electrical wire
