Improved sustainability
is associated with elastomers that readily
breakdown in the environment at end of life and, as importantly, that
can be reprocessed/reused long before end of life arises. We report
the preparation of silicone elastomers that possess both thermoplasticityreprocessabilityand
antioxidant activity. A combination of ionic and H-bonding links natural
phenolic antioxidants, including catechol, pyrogallol, tannic acid,
and others, to telechelic aminoalkylsilicones. The mechanical properties
of the elastomers, including their processability, are intimately
linked to the ratio of [ArOH]/[H2NR] that was found to
be optimal when the ratio exceeded 1:1.
