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 Fulltext... Hierarchy... Expanded...C08F, silicone rubbers, polyalkylene polysulphides and isocyanate modified polyamides will be found in Fulltext... Hierarchy... Expanded...C08G, factice in Fulltext... Hierarchy... Expanded...C08H and liquid polymers of conjugated dienes in Fulltext... Hierarchy... Expanded...C08F.
