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...
