Abstract
Rubber compositions of a selected base rubber and a specified paraffin was containing 50% or more of a normal paraffin and having a carbon area ratio of less than 4.0 as determined by gas chromatography within a carbon number range of from 23 to 42. The ratio is derived by counting a first paraffin content which is defined by the paraffin of maximum content in the wax and a second paraffin content which is defined by the paraffin of minimum content in the wax and thereafter dividing the first paraffin content by the second paraffin content. The composition is highly stable in initial tack with less dependence on temperature before curing.
