The gully closure for preventing the pollution of bodies of water in accident situations consists of a flexible mat (1) which covers the gulley surface and is coated with a highly viscous, free-flowing moulding composition (2). A plastically deformable silicone gel has proved particularly successful as a free-flowing moulding composition (2).

Thermosetting organopolysiloxane compositions

A process for the production of polymeric organosiloxanes comprising reacting diorganosiloxanes with substances regulating the chain length in the presence of alkaline and/or acid reaction catalysts and wherein the polymerization takes place in a reactor consisting of several zones and is provided with stirring or conveying elements, the arrangement of the stirring or conveying elements being such that the flow of material produced by the stirring or conveying element in each zone is the opposite of that in the adjacent zone or zones.

Process for the continuous preparation of polydiorganosiloxanes

A polysiloxane composition which can be cross-linked under atmospheric conditions and which consists essentially of: A. 100 parts by weight of an .alpha.,.omega.-dihydroxymethylphenylpolysiloxane with about 7-15 mole % of diphenylsiloxy units or about 14-28 mole % of methylphenylsiloxy units, and having a viscosity of between about 1,000 and 500,000 cSt (at 20.degree. C), b. about 1 to 40 parts by weight of an uncoated reinforcing filler consisting essentially of SiO.sub.2 having a specific surface area of about 40 to 500 m.sup.2 /g by the BET method, and C. about 1 to 10 parts by weight of a cross-linking agent of the formula
