Abstract

Polysiloxanes suitable to render porous surfaces hydrophobic are prepd. using a two component initial reaction mix comprising cpds. of general formula R(a)nSi(OR)pClq - where R(a) = an alkyl, alkylene substd. alkyl, aromatic or substd. aromatic gp. linked via a silicone-carbon bond; R = 1-4C straight or branched chain alkyl gp.; n = 0,1,2 or 3; p and q = 0,1,2,3 or 4 with the restriction that n+p+q = 4 - and cpds. of general formula R(a)nSi(OR)pClq(OX)r - where X = ethyl-, n-propyl, i-propyl gps. substd. by chlorine; n = 0,1 or 2; p and q = 0,1,2, or 3 provided p+q = 0; r = 1 or 2 but n+p+r+q = 4. Reaction occurs in presencee of usual catalysts. The product is applied either directly or in an organic solvent to porous surfaces of surfaces of large specific areas as claddings for buildings, fibres, fibre bundles, and powdery substances.
