Alkene Isomerization as an Entry to Efficient Alternating Ring-opening Metathesis Polymerization (iAROMP)


Most sequence-controlled polymers lack rigorous fidelity or are homopolymers with simple chain microstructures or copolymers, in which the monomer sequence is not precisely controlled. Polymers of imprecise sequence are widely employed, but do not provide the same structural and functional complexity as sequence-controlled biopolymers created by nature. This invention provides a facile approach to prepare extremely long and completely alternating copolymers.


Scientists at Stony Brook University have created an invention which enables the preparation of polymers in which the backbone has a regular alternating pattern of functional group arrangement. The backbone has additional constraints incorporated that provide a new polymer architecture. This technology allows the delivery of equal amounts of two compounds and the polymers created have a low dispersion of molecules and long lengths.
