Abstract
A method includes the steps of (I) fabricating a cured silicone product and (II) using the cured silicone product in a patterning technique. The cured silicone product is a reaction product of (A) a silicone cure package and (B) is a polar additive having a polyalkylene oxide functionality and a reactive functionality. The method is useful in soft lithography applications.
