Abstract
1310353 Pelleted organopolysiloxane curable compositions DOW CORNING Ltd 22 June 1970 [26 June 1969] 32225/69 Heading C3T A curable composition comprises (1) a polydiorganosiloxane having per molecule at least two Si-bonded hydrocarbon radicals containing aliphatic unsaturation, (2) a compound containing per molecule at least two Si-bonded H atoms, and (3) a catalyst for the reaction between (1) and (2), and is in the form of pellets any one of which contains not more than two of the components (1), (2) and (3). Suitable unsaturated and other organo groups for (1) are listed; preferably (1) contains MeViSiO and/or Me 2 ViSiO 1 / 2 units with Me 2 SiO and optionally MePhSiO or CF 3 CH 2 CH 2 SiMeO units and/or Me 3 SiO 1 / 2 or Me 2 PhSiO 1 / 2 units. Component (2) may be, e.g. a silane, silcarbane, cyclosiloxane or silcarbane-siloxane copolymer, but is preferably a linear polysiloxane of e.g. MeHSiO units with Me 2 SiO, MePhSiO and Me 3 SiO 1 / 2 units. The ratio of Si-bonded H to unsaturated groups is preferably 2-10 : 1. Suitable catalysts (3) include Pt, Ru, Rh, Pd, Ir, Pt salts and complexes, and Fe, Ni and Co carbonyls. Conventional fillers (listed) may be present. Preferably (2) and (3) are not present in the same pellet. In Example 1 a trimethylsiloxy-terminated polydimethylsiloxane of MW 200,000 containing 0À33 wt per cent MeViSiO units is compounded with carbon black and (A) a trimethylsiloxy-terminated methylhydrogen siloxane of MW 3000 or (B) an H 2 PtCl 3 .6H 2 O- 1 : 3 - divinyl - 1 : 3 - dimethyldisiloxane complex to give pellets which are mixed in equal weight. In Example 2 pellets (C) prepared as (A) above with calcium silicate filler are mixed in 8 : 155 weight ratio with pellets (D) prepared as (B) above with methylethylketoxime added. In Example 3 pellets are prepared from a similar vinyl-containing polysiloxane, fume silica and a polydimethylsiloxane diol plasticizer compounded with (F) the above methylhydrogensiloxane or (G to K) solutions in CH 2 Cl 2 of Pd acetylacetonate, diethylene Rh(I) acetylacetonate, bis - (tri - n - butylphosphine) - PtCl 2 , Ir acetylacetonate or Ru acetylacetonate; pellets (F) are mixed in 1 : 1 weight ratio with pellets (G) to (K).
