摘要

In this paper we present a poly siloxane containing covalently bound indoaniline dye, which decolorizes during reaction with a poly siloxane bearing vinyl and Si-H groups in the presence of a Karstedt catalyst. Poly siloxane bearing indoaniline endgroups were prepared from (2-allyl-4-(4-(ethyl(2-hydroxyethyl)amino)phenylimino)-6-methoxycyclohexa-2,5-dienone respectively 2-allyl-4-(4-(ethyl(2-hydroxyethyl)amino)phenylimino)cyclohexa-2,5-dienone) and Si-H terminated poly siloxane. The structure was verified by IR-, ~1H-NMR spectroscopy, and MALDI-TOF mass spectrometry. The obtained blue colored poly siloxane is suitable as dye indicator for crosslinking, for example, for a time-controlled preparation of dental impressions.
