Then, an excess of diphenyl phosphate was introduced for the second polymerization of TMC. Metal-free organic catalysts for ring-opening polymerization of TMC were used to prepare star-shaped ...

Plastic waste is a growing environmental crisis, with thermosets among the most problematic materials. These durable plastics, used in car tires, replacement hip joints, and aerospace coatings, resist ...

Finally, we are developing monomers with minimal polymerization shrinkage and applying ring-opening polymerization methods to obtain practical expanding monomers. Dimensionally stable polymerizations ...

Molecular subunits link to produce polymer chains that can connect through their backbones and cross-linked molecules to form ...

Thus, the ring-opening co-polymerization of two different cyclic esters leads, in most cases, to the formation of polymer chains with ill-defined sequence distributions. Thomas and his colleagues ...

Upcycling may help remedy the roughly 450 million tons of plastic discarded worldwide annually, of which only nine per cent ...
