Abstract:
1. A process for condensation between at least one ≡SiOH unit and at least one ≡SiOR unit with R representing a hydrogen or a C 1 -C 20 hydrocarbon group optionally comprising one or more heteroatoms, said ≡SiOH and ≡SiOR units belonging to at least one identical or different (organo)silicon compound P, in the presence of an effective amount of at least one catalyst C, comprising a carbine, wherein: a) the (organo)silicon compound P is a polyorganosiloxane corresponding to formula A with: b) the (organo)silicon compound P is a silicon-comprising compound B which is a silane of following formula (B): in which: c) the (organo)silicon compound P is a polyorganosiloxane resin D, functionalized by at least one Y′ radical wherein Y′ represents identical or different —OR′ groups, with R′ having the same definition as R and wherein, the catalyst C corresponds to the formula (II) or (II′): in which: in which: the T
