Low molar mass (3–17 kg/mol) amino-telechelic polyethylene (ATPE) was used to reactively compatibilize poly(ethylene terephthalate) (PET) and high-density polyethylene (HDPE) via ester aminolysis of PET. A tert-butyloxycarbonyl (Boc)-protected poly

The effect of S-acetylation in MN2S2 complexes on metal exchange reactivity was examined in a series of MN2S2O2 complexes. While clean exchange processes do not occur for the MN2S2 derivatives where formation of S-bridged aggregates predominate, acet
