In some cases chain transfer agents are added to reaction mixture or to control the Molecular weight of the polymers. Mercaptans are used for this purpose. The modifying action of sulphur compounds is much greater than most of the solvents. The modifying action of diisopropylxanthate disulphide in the synthesis of SBR (styrene butadiene rubber) can be shown as under ... [Pg.33]

BUTADIENE. [CAS 106-90-0]. CHrCH C CH3, 1,3-butadiene (methyl-allene), formula weight 54.09. bp —4.41cC, sp gr 0.6272, insoluble in H2 O. soluble in alcohol and edier in all proportions, Butadiene is a very reactive compound, arising from its conjugated double-bond structure. Most butadiene production goes into die manufacture of polymers, notably SBR (styrene-butadiene rubber) and ABS (acryloiiitrile-buladiene-slyrene) plastics. Several organic syntheses, such as Diels-Alder reaction, commence with the double-bond system provided by this compound. [Pg.262]

The emulsion SBR (styrene-butadiene rubber) developed in the 1940s, utilizing free-radical initiation, was of enormous benefit to tire technology. The improvement in performance and cost of SBR over natural rubber in tire treads firmly established the utility of synthetic rubber. The success of emulsion SBR led to further research. As a result, the percentage of natural rubber in rubber produced since that time has been steadily declining, and extensive research efforts have been carried along on a continuing basis to develop even better synthetic elastomers.

Isobutene is used in the field of elastomers, mainly to manufacture a special rubber, butyl rubber, by copolymerization with small amounts of isopiene. It serves essentially for the manufacture of inner tubes, but its production remains modest and accounts for barely 10 per cent of that of SBR (Styrene Butadiene Rubber). Isobutene is also used to produce additives for oils (polyisobutenes), detergents (di- and triisobutylenes) and cur rently for the manufacture of MTBE. [Pg.339]
