A few years back (2003) I posted some information regarding nitrile
gloves to the DistList.  In short, not all nitrile gloves are
created equal.  Some are manufactured with a polymer coating, while
some are manufactured via a process of chlorination and subsequent
sulfur reduction.  Depending on the manufacturer, the chlorinated
gloves proved problematic due to residual sulfur from the reduction
phase of manufacturing.

I haven't done any further research into this, but hopefully this
information will prove helpful.
