KR20110015577A - Dip-formed synthetic polyisoprene latex
The synthetic polyisoprene latex emulsion of the present invention has a pre-vulcanization composition and a post-vulcanization composition. The pre-vulcanization composition includes soluble sulfur having a higher S 8 ring structure that is catalytically destroyed by zinc dithiocarbamate. Latex emulsions have a post-vulcanization composition with an accelerator that crosslinks the intergranular region during the post-vulcanization cure cycle.
