A process of reducing the effects of moisture during storage prior to vulcanization of a vulcanizable halogen-containing polymer composition containing water, comprising blending before storage, into said vulcanizable composition, a thioester derivative of 2,5-dimercapto-1,3,4-thiadiazole crosslinking agent and glycerin, whereby the scorch time of the vulcanizable compound is not significantly affected by the water content of said composition. In addition, a vulcanizable halogen-containing polymer composition comprising a thioester derivative of the crosslinking agent and glycerin, and a dry pourable powder cure premix composition comprising the crosslinking agent, glycerin and a pourable siliceous finely divided filler.
