<p>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 1,4-butanediol, 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 the crosslinking agent and 1,4-butanediol, and a dry pourable powder cure premix composition for inclusion in a halogen-containing vulcanizable polymer composition, comprising the crosslinking agent, 1,4-butanediol and a pourable siliceous finely divided filler.</p> |
