The present invention relates in part to compositions displaying stress relaxation at the polymer-filler interface. The adaptive interface (AI) formed by coupling moieties capable of dynamic covalent chemistry (DCC) within the polymer-filler interface promotes stress relaxation and yields tough, and healable composites.
title compound 1,3,4-triphenyl-4,5-dihydro-1H-1,2,4-triazol-5-ylidene (1), a stablecarbene, is chemically characterized via its reactivity towards a multitude of organic substrates. Its behaviour in insertion, addition and cycloaddition reactions allows its classification as a typical representative of nucleophilic carbenes.
