520			_aSurface treatment of prevulcanised latex film with ozone water leads to the formation of ester, aldehyde, and ketone groups as indicated by a FTIR-ATR study. In the presence of proteins, the carbonyl oxide zwitterion intermediate reacts with the amino groups of the protein to produce rubber-bonded proteins on the surface. In the case of ozone-treated wet rubber gel, the tensile strength of the film remains high, indicating no significant ozone penetration. The reaction of ozone with natural rubber in the wet gel state may be used ot chemically modify the surface of natural rubber products without sacrificing the excellent physical properties of the rubber.
