Abstract

The invention relates to polysiloxanes from cross-linkable monomers based on cyclosiloxanes and their use in polymerizable compositions. The invention relates in particular to polysiloxanes from sol-gel-condensable cyclosiloxane(meth)acrylates as well as resinous compositions, obtainable by hydrolytic condensation of one or more hydrolyzable and condensable cyclosiloxane(meth)acrylates.
