STABILIZATION OF CROSS-LINKED SILANE GROUP CONTAINING POLYMERS

摘要

The present invention relates to a composition for cross-linking and stabilization of a polymer containing hydrolysable silane groups comprising a sulphonic acid as a silan ol condensation catalyst characterized in that it comprise a stabilizer which is neutral or acidic, does not contain ester groups and is a compound according to formula (II): wherein R' '' is an aliphatic hydrocarbyl radical and p is 1 to 6; or a mixture of any of such compounds, to a stabilized polymer comprising the above stabilizers and to a process for cross-linking and stabilization of silane group containing polymers in the presence of the above mentioned stabilizers.
