example
[0255] The following examples are intended to illustrate exemplary embodiments within the scope of the invention. Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as possible. Any numerical value, however, inherently contains certain errors necessarily resulting from the standard deviation found in their respective testing measurements. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques.
[0256] test program

example 1-
[0286] Example 1 - Pressure Sensitive Adhesive
[0287] Pressure-sensitive adhesive samples were prepared by scanning pulsed electron beam irradiation with paste A at a temperature of 0 °C. Each sample was coated to a thickness of approximately 1 mil (25 microns thick) using a Meyer rod and sandwiched between two layers of 1 mil (25 microns thick) polyethylene terephthalate film (PET) between.
[0288] The percent conversion and percent gel were measured for each coated sample. Example 1 shows the effect of dose per exposure duration on the total dose required to obtain an extrapolated conversion rate of at least 90%, and more preferably at least about 95% or higher (e.g., 94.4% to 99.7%) . Example 1 also shows that the dose for each duration of exposure contributes to obtaining at least about 80%, more preferably at least about 90%, or even at least about 95% (e.g., 97-99.1%) but preferably less than 100% of the extrapolated coagulation. Effect of the total dose require...

[0295] Example 2 - Silicone Crosslinking
[0296] The sample conditions described above were also used to crosslink non-functionalized PDMS (OHX-4070, 50,000 centistokes) coated on PET to a thickness of 3 mils (75 microns). Table 2 summarizes the experimental conditions and results (percent gel) for crosslinking.
