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.

DOI: 10.1021/acs.macromol.8b00705

Abstract: Selectively main chain 13C-labeled poly(p-phenylenevinylene)s (PPVs) were synthesized by ring-opening metathesis polymerization (ROMP) of 13C-labeled dialkoxy-substituted [2,2] paracyclophane-1,9-dienes (M) using the Grubbs second generation ruthenium carbene complex (G2). Analysis of the natural abundance and 13C-labeled… read more here.
