Patent ID: 7297718

Claim:
A method of producing substantially spherical lyogels comprising the steps of: a) providing a lyosol, b) transferring the lyosol provided in step a) to at least one silylating agent in which the lyosol is insoluble to form a substantially spherical lyosol, and c) gelling the substantially spherical lyosol formed in step b) in at least one silylating agent in which the substantially spherical lyosol is insoluble, to produce the substantially spherical lyogel, wherein the silylating agent in steps b) and c) comprises at least one disiloxane of formula (I) R 3 Si—O—SiR 3 (I) the radicals R being, independently of each other, identical or different, each denoting a hydrogen atom or a non-reactive, organic, linear, branched, cyclic, saturated or unsaturated aromatic or heteroaromatic radical, and wherein the lyosol in step b) is transferred dropwise.
