Abstract
The effect of residual diethyldithiocarbamate on the environmental degradation of prevulcanised natural rubber latex films was studied in the presence of zinc oxide and a conventional phenolic antioxidant. The films were buried in a clayey soil at 40 field capacity and retrieved after 24 and 48 weeks. The overall degradation was significantly greater for films without zinc oxide and without Wingstay L as well as for films prepared at longer vulcanisation process times. Films prepared with zinc oxide and Wingstay L showed generally smooth surfaces after 24 weeks compared to films prepared without zinc oxide or Wingstay L that had cracks and voids across the surfaces. The concentrations of residual dithiocarbamates remaining could offer an explanation as to why some of the film pieces were slow to degrade despite the higher degree of crosslinking formed.
