    Abstract: Low dielectric constant curable compositions include a first alkyl (meth)acrylate monomer with 12 or more carbon atoms, a crosslinking monomer, a copolymeric additive of a polycarbosilane or a polycarbosiloxane, and at least one initiator. The curable composition is solvent free and inkjet printable. Upon curing the curable composition forms a non-crystalline, optically transparent layer with a dielectric constant of less than or equal to 3.0 at 1 MegaHertz.

    Abstract: A dihaloorganosilane is represented by the formula (I): Each X independently represents Cl, Br, or I. Each Ar1 independently represents a phenylene group optionally substituted by 1 to 4 alkyl groups selected from methyl or ethyl. Each R1 independently represents an alkylene group having from 2 to 18 carbon atoms. Each R2 independently represents methyl or ethyl. Each R3 independently represents an alkylene group having from 1 to 18 carbon atoms. Each R4 independently represents an alkylene group having from 2 to 18 carbon atoms, and n is an integer in a range of 0 to 5, inclusive. Ionic organosilanes preparable from the dihaloorganosilanes are represented by the formula (II): Membrane compositions and membranes containing the ionic organosilanes are also disclosed.

    Abstract: Curable silsesquioxane compositions, include three dimension networks of Formula I, Formula II, or a combination of Formula I and Formula II, where the oxygen atom at the * is bonded to another Si atom, R is a fluorinated organic group, R2 is an ethylenically unsaturated organic group, n+m is greater than 3, and the —OH groups are present in an amount of at least 15 wt-% of the network. The curable composition may also include a silanol-terminated fluorinated polysiloxane fluid. The curable composition is a coatable composition that is solvent free and wets glass. The curable composition, when cured, has a refractive index of 1.40 or lower.
