摘要： A gel has improved thermal stability and is the ultraviolet hydrosilylation reaction product of (A) an organopolysiloxane having an average of at least 0.1 silicon-bonded alkenyl group per molecule and (B) a cross-linker having an average of at least 2 silicon-bonded hydrogen atoms per molecule. (A) and (B) react via hydrosilylation in the presence of (C) a UV-activated hydrosilylation catalyst comprising at least one of platinum, rhodium, ruthenium, palladium, osmium, and iridium, and (D) a thermal stabilizer. The (D) thermal stabilizer is present in an amount of from about 0.01 to about 30 weight percent based on a total weight of (A) and (B) and having transparency to UV light sufficient for the ultraviolet hydrosilylation reaction product to form.

摘要： A hydrosilylation process is used to prepare a clustered functional polyorganosiloxane. The clustered functional polyorganosiloxane comprises a reaction product of a reaction of a) a polyorganosiloxane having an average, per molecule, of at least 2 aliphatically unsaturated organic groups; b) a polyorganohydrogensiloxane having an average of 4 to 15 silicon atoms per molecule; and c) a reactive species having, per molecule at least 1 aliphatically unsaturated organic group and 1 or more radical curable groups selected from an acrylate group and a methacrylate group; in the presence of d) a hydrosilylation catalyst, and e) an isomer reducing agent. The weight percent of silicon bonded hydrogen atoms in component b) divided by the weight percent of aliphatically unsaturated organic groups in component a) (the SiHb/Via ratio) ranges from 4/1 to 20/1. The resulting clustered functional polyorganosiloxane is useful in a curable silicone composition for electronics applications.
