SYNTHETIC RUBBERS
 C08D

Note(s)

For the purpose of this classification system, the term "synthetic rubbers " is restricted to rubbery vulcanisable products obtained by the polymerisation of a conjugated diene, if desired together with one or more other unsaturated monomers. Thus, polyisobutylene (which is not vulcanisable) will not be found here but in C08F, silicone rubbers, polyalkylene polysulphides and isocyanate modified polyamides will be found in C08G, factice in C08H and liquid polymers of conjugated dienes in C08F.

Note(s)

This sub-class covers polymerised unsaturated condensation products.
