The objective of this study was to develop a pressure sensitive adhesive (PSA) from epoxidized skim
rubber (E-LPSR) obtained from saponified low protein skim rubbe r(S-LPSR) and blended with poly (vinyl
alcohol) (PVA) containing atackifier,via solution and emulsion,respectively.The creep properties of PSA
and E-PSA in the presence of a 60 hydrocarbon resin were improved by addition of 10 phr of PVA but the
surface free energy,tack strength and peel strength of the two adhesives weres lightly decreased.The
optimal concentration of PVA for agood pressure-sensitive adhesive was found to be20phr because of
its emulsion.
