The present invention provides a modified sulphur composition comprising: a first modified sulphur prepared by admixing molten elemental sulphur with one or more olefinic sulphur modifiers selected from, for example, the group consisting of norbornenes, dicyclopentadiene, cyclopentadiene, oligomers of dicyclopentadiene; and a second modified sulphur prepared by admixing molten elemental sulphur with one or more olefinic sulphur modifiers selected from styrene and derivatives thereof, dicyclopentadiene, cyclopentadiene, dipentene, oligomers of dicyclopentadiene, naphthalene and limonene. The first modified sulphur is different than the second modified sulphur. |
