Catalyst-free vitrimers have attracted attention for practical application of vitrimer concept, which requires fundamental knowledge on phys. property tuning. We prepared catalyst-free vitrimers by crosslinking amorphous polyesters bearing COOH side groups with tetra-epoxy compounds bearing tertiary amines (4,4′-methylenebis(N,N-diglycidylaniline), abbreviated as Mb-epoxy). The obtained network possessed ester and OH groups, and the amino moieties worked as internal catalysts for trans-esterification-based bond-exchange. The competing effect of crosslink d. and concentration of amines was investigated for samples with different fractions of Mb-epoxy, revealing that crosslink d., which governs chain mobility, was the dominant factor in the determination of bond-exchange rate. The experimental process involved the reaction of Pentane-1,5-diol(cas: 111-29-5).Category: alcohols-buliding-blocks
