Patent ID: 8536295

Claim:
A polymer formulation comprising: a soluble, stable and non-gelled, curable silicon-containing polymer comprising repeat units selected from the structural formulae (III)-(VII) [R 1 Si(OH)O] k (III) [R 1 Si(OR 10 )O] m (IV) [R 1 SiO 1.5 ] n (V) [R 1 Si(H)O] p (VI) [R 2 R 3 SiO] q (VII) wherein: k, m, n, p and q represent the fraction of repeat units of the silicon-containing polymer that have the structural formula (III), (IV), (V), (VI), and (VII) respectively, provided that: (a) n has a value between 0 and about 0.5; (b) q has a value between 0 and about 0.2; (c) m has a value between 0 and about 0.5; (d) k has a value between 0.05 and 0.95; and (e) p has a value that is less than about 0.1 if a catalyst capable of activating Si—H bonds and a curing agent or functional group are present in the formulation, and less than 0.95 otherwise; R 1 is C 1 -C 30 hydrocarbyl which is optionally substituted and is optionally heteroatom containing; R 2 and R 3 are independently selected from H, C 1 -C 30 hydrocarbyl, organometallic, halocarbyl, and organosilyl, each of which is optionally substituted and is optionally heteroatom-containing; and R 10 is selected from C 1 -C 30 hydrocarbyl, organometallic, halocarbyl, and organosilyl, each of which is optionally substituted and is optionally heteroatom containing, wherein k is 0.65, p is 0.35, m, n and q are 0 and R 1 is phenyl, and the formulation is a viscous liquid having the following formula: [PhSiO(H)] 0.35 [PhSiO(OH)] 0.65 .
