Chlorinated isoprene rubber and also PVC which is described next react not only as a chlorine donor, but also as a fuel They are, however, different from each other regarding the extent of their reaction as a fuel. According to experiments it may be assumed in practice that the rubber is only a chlorine donor, but PVC is both a chlorine donor and a fuel when they are used for chlorate or perchlorate based compositions.

With barium nitrate alone as the oxidizer the composition does not burn quickly and creates a large amount of ash. To avoid this, potassium perchlorate is added to the composition. The chlorinated isoprene rubber intensifies the green colour of the flajne.

For the iodate method, chlorine in concentrations below 1 mass % does not interfere. The isoprene rubber method can tolerate somewhat higher levels. Nitrogen when present above 0.1 mass % may interfere with the iodate method, the extent depending on the types of nitrogen compounds as well as the combustion conditions. It does not interfere in the infrared method. The alkali and alkaline earth metals, zinc, potassium, and lead do not interfere with either method. 

More recently, the dehydrohalc enation of chlorinated butyl rubber, i. e. iso-butene-isoprene copolymer containing 1.4—1.6 wt % of chlorine, essentially in allylic positions, was performed successfully thus poljdsobutraie chains carrying randcxn groups of two conjugated double bonds were obtained. 

The introduction of conjugated diene functions in polyisobutene chains has been recently acconq>lished throu an indirect approach which utilizes the dehydro-haiogenation of chlorinated butyl rubber, i. e. randomly chlorinated poly(isobutene-co-isoprene), by means of basic agents ...

Halobutyl rubber (HIIR) is used primarily in tire innerliner and white sidewalls. These elastomers are best for tire air retention owing to lower air permeability as well as aging and fatigue resistance. The chlorinated (CIIR) and brominated (BUR) versions of isobutylene isoprene rubber (HR) can be blended with other elastomers to improve adhesion between HIIR compounds and those based on general purpose elastomers, and improve vulcanization kinetics [16].

In this chapter, a possibility of chlorinated natural robber and isoprene rubber epoxy dation by means of ozonation is investigated with the aim of improving adhesion characteristics of glnes based on these rubbers as it is known that epoxy compounds are good film-formers in glue compositions and increase the overall viscosity of the last ones.
