    Abstract: A hydrosilylation process is used to prepare a polyorganosiloxane having clustered functional groups at the polyorganosiloxane chain terminals. The ingredients used in the process include a) a polyorganosiloxane having an average of at least 2 aliphatically unsaturated organic groups per molecule, b) a polyorganohydrogensiloxane having an average of 4 to 15 silicon atoms per molecule and at least 4 silicon bonded hydrogen atoms for each aliphatically unsaturated organic group in ingredient a), c) a reactive species having, per molecule at least 1 aliphatically unsaturated organic group and 1 or more curable groups; and d) a hydrosilylation catalyst. The resulting clustered functional polyorganosiloxane is useful in a curable silicone composition for electronics applications.

    Abstract: A polymer cures by either radiation or moisture curing mechanisms, or both. The polymer is prepared by hydrosilylation. The polymer includes units of formula: (R22Si02/2)b, (R2Si03/2)c, (SiO4/2)d, (R1′)f, and (R23Si01/2)g, where each R1 is independently an oxygen atom or a divalent hydrocarbon group; each R1′ is independently divalent hydrocarbon group; each R2 is independently a monovalent organic group that is free of terminal aliphatic unsaturation each X is independently a monovalent hydrolyzable group; each J is independently a monovalent epoxy functional organic group; subscript a has a value of 1 or more; subscript b has a value of 0 or more; subscript c has a value of 0 or more; subscript d has a value of 0 or more; subscript e has a value of 1 or more; subscript f has a value of 0 or more; subscript g has a value of 0 or more; subscript s is 1, 2, or 3; and subscript t is 1, 2, or 3.
