Synthesis of trithiocarbonates and allyl sulfides and their application into advances in covalent adaptable networks
Monomers having a C-B-A-B-C structure are disclosed, where A is a core of either trithiocarbonate and allyl sulfide, where B are linker units, and where C are end units. The end units may comprise acrylates, methacrylates, alcohol(s), amine(s), and alkynes, among others. The linker units may include an alkane, alkene, phenyl, diphenyl, or benzylic group, among others. Methods of synthesizing such compounds are also disclosed.
