Patent ID: 8110612

Claim:
An adhesive composition made according to a process comprising: introducing primary raw materials comprising a non-thermoplastic elastomer into a feeding section of a planetary roller extruder; conveying the primary raw materials from the feeding section to a compounding section of the planetary roller extruder; mixing the primary raw materials in the compounding section; providing a first means of crosslinking by adding a heat-activatable crosslinker to the compounding section; providing a second means of crosslinking by adding an ionizing radiation crosslinker to the compounding section; continuously producing a homogeneous adhesive composition while maintaining the temperature of the adhesive composition between about 25° C. and 100° C.; applying the homogeneous adhesive composition to a web-form material; and exposing the web-form material with the applied composition to ionizing radiation thereby crosslinking the adhesive composition with the ionizing radiation crosslinker; wherein the non-thermoplastic elastomer is masticated during mixing in the compounding section such that its M w is reduced by about 50% to about 80% and the heat-activatable chemical crosslinker remains generally unactivated such that it is a residual latent curing agent available for later activation.
