    摘要: A silicone hybrid pressure sensitive adhesive composition that cures to form a silicone hybrid pressure sensitive adhesive contains a polydiorganosiloxane having reactive groups. The reactive groups include a silicon bonded (meth)acryloxyalkyl-functional group in a pendant position and optionally a silicon bonded aliphatically unsaturated hydrocarbon group in a terminal position. The silicone hybrid pressure sensitive adhesive composition can be cured via hydrosilylation reaction on a surface of a substrate to form a protective film. The protective film can be used to protect a passivation layer during a process for fabricating an (opto)electronic device such as a flexible organic light emitting diode display. The protective film can be exposed to radiation to reduce tack and facilitate detaching the protective film from the passivation layer.

    摘要: A cationic surfactant is disclosed. The cationic surfactant has the general formula [Z-D-N(-D1-NR13+)a(R)2-a][X−]a where Z is a siloxane moiety or an unsubstituted hydrocarbyl moiety having from 5 to 20 carbon atoms, D is a covalent bond or a divalent linking group, D1 is a divalent linking group, R is H or an unsubstituted hydrocarbyl group having from 1 to 4 carbon atoms, each R1 is an independently selected unsubstituted hydrocarbyl group having from 1 to 4 carbon atoms, subscript a is 1 or 2, and each X is an anion. A method of preparing the cationic surfactant is also disclosed.
