DOI: 10.1002/marc.201700735
Abstract: Metal-free entropy-driven disulfide metathesis polymerization of unsaturated l-cystine based macrocycles produces high-molar-mass heterofunctional poly(disulfide)s, i.e., poly(ester-disulfide-alkene) and poly(amide-disulfide-alkene); Mwapp = 44-60 kDa, Ð > 1.7. The polymerization is fast and reaches equilibrium within 1-5 minutes… read more here.
