Title: POLYMER COMPOSITION COMPRISING CROSSLINKED SILICONES WITH EXCHANGEABLE CROSSLINKING POINTS, PREPARATION METHOD AND USES
Abstract:
The invention concerns a silicone composition comprising (a) polymers comprising consecutive crosslinked -Si-O- units containing exchangeable pendant bonds and exchangeable crosslinking points, that are exchangeable by aldehyde-imine exchange reactions and/or by imine-imine exchange reactions and/or by imine-primary amine exchange reactions, obtained by crosslinking polymers comprising consecutive linear or branched -Si-O- units and (b) monofunctional free aldehydes and/or monofunctional free imines and/or monofunctional free primary amines.
