  1. 1
    Volatile silicon compounds characterized in that they have a boiling point of no greater than about 260°C at 760mm, and comprise the following structures:a) Linear siloxanes where 1) X = 1 to 4, 2) total carbons ≦ 14, 3) R can be independently C₁-C₁₀ alkyl, trialkyl siloxy and 4) at least one R per molecule must be selected from R₁ R₂ where R₁ = C₁-C₄ alkylene and R₂ = -O-R₃ wherein R₃ = C₁-C₅ alkyl or C₁-C₇ ketone or b) Cyclic siloxanes wherein 1) Y = 3 to 6, 2) total carbons ≦14, 3) R can be independently C₁-C₁₀ alkyl and 4) at least one R per molecule must be selected from - R₁ R₂ where R₁ = C₁-C₄ alkylene and R₂ = - O - R₃ where R₃ = C₁-C₅ alkyl or -C₁-C₇ ketone or c) Silanes wherein 1) Z = 1 to 4, 2) total carbons ≦14, 3) R can be independently C₁-C₁₀ alkyl, trialkyl (C₁-C₃) siloxy and 4) at least one R per molecule must be selected from - R₁ R₂ where R₁ = C₁-C₄ alkylene and
