ABSTRACT:
Block polymer compositions are provided which are useful as positive or negative resists utilizing aryl onium salts in combination with silicone-organic block polymers, such as polydimethylsiloxane-poly-t-butylmethacrylate block polymers. A silicone prepolymer is used in combination with certain polymerizable vinyl monomers such as t-butylmethacrylate. The silicone prepolymer has chemically combined pinacolate groups in the backbone or terminal positions which are capable of generating free-radicals upon thermolysis.
