Abstract
Use of solid, rubber-soluble or rubber-dispersible monothiols as stabilizers in melted pressure-sensitive adhesive compositions based on natural rubber or synthetic rubbers, suitable tackifying resins and promoters for increasing the radiation crosslinking yield.
Claims6
Pressure-sensitive adhesive composition comprised of natural rubber or synthetic rubbers, tackifying resins, promoters for increasing the radiation crosslinking yield, an antioxidant consisting essentially of a rubber-soluble or rubber dispersible monothiol and, optionally, at least one liquid phosphite ester compatible with the rubber.
A method for stabilizing a melted pressure-sensitive adhesive composition comprised of natural or synthetic rubber, a tackifying resin and a promoter for increasing the radiation crosslinking yield, which comprises adding an antioxidant consisting essentially of a solid, rubber-soluble or rubber-dispersible monothiol to said composition as an antioxidant.
