A process for the cross-linking or chain-extension of hydrocarbon polymers which contain ethylenically unsaturated groups which comprises forming an intimate mixture of the polymer with a mono-sulphonyloxycarbamate of the formula: A -- O -- CO -- NH -- O -- SO.sub.2 R (1) wherein A is an alkyl group, a cycloalkyl group, an alkenyl group, a substituted alkyl group, a substituted aryl group or a heterocyclic group, and R is an optionally substituted alkyl or aryl group. The process is useful for natural and synthetic rubbers. The rate and extent of cross linking may be modified by the additives such as tertiary amines or conventional rubber additives e.g. tetramethyl and zinc diethyl dithiocarbamates, which contain tertiary amino groups.

A process for the cross-linking or chain extension of hycrocarbon polymers which contain ethylenically unsaturated groups which comprises forming an intimate mixture of the polymer with a carbamate of the formula: ##STR1## WHEREIN R.sub.1 is an optionally substituted hydrocarbyl radical, m is an integer, and A is H or an optionally substituted hydrocarbyl radical of valency m, and subjecting the mixture to heat. Novel compounds of preferred use include those in which m=1 and at least one of R and A is alkyl or 7 or more carbon atoms, or in which m=2 and A is phenylene or alkylene or alkenylene of 2 to 4 carbon atoms.
