    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.

    Abstract: Free-radical initiators are provided in the form of silylethers of arylpinacols. An aryl ketone is reacted with a monohalo- or dihalosilane having at least one olefinically unsaturated organic radical attached to silicon in the presence of an active metal reducing agent, such as magnesium.

    Abstract: Onium salts of Group VIa elements having an MF.sub.6.sup.- anion, where M is selected from P, As and Sb, have been found to be photo active under ultraviolet light. These onium salts can be employed as cationic photoinitiators when used with a variety of organic resins and cyclic organic compounds.
