A General Approach to Sequence-Controlled Polymers Using Macrocyclic Ring Opening Metathesis Polymerization
A new and general strategy for the synthesis of sequence-defined polymers is described that employs relay metathesis to promote the ring opening polymerization of unstrained macrocyclic structures. Central to this approach is the development of a small molecule "polymerization trigger" which when coupled with a diverse range of sequence-defined units allows for the controlled, directional synth...
متن کاملCatalytic living ring-opening metathesis polymerization.
In living ring-opening metathesis polymerization (ROMP), a transition-metal-carbene complex polymerizes ring-strained olefins with very good control of the molecular weight of the resulting polymers. Because one molecule of the initiator is required for each polymer chain, however, this type of polymerization is expensive for widespread use. We have now designed a chain-transfer agent (CTA) cap...
متن کاملSolid-phase synthesis of polymers using the ring-opening metathesis polymerization.
We report a general method for the solid-phase synthesis of polymers via the ring-opening metathesis polymerization (ROMP). The method involves polymerization in solution to form a block copolymer, immobilization of the polymer via reaction of one block with a resin-bound functional group, modification of the other block, and liberation of the polymer from the resin. We demonstrated the utility...
متن کاملSynthesis of High Performance Cyclic Olefin Polymers (COPs) with Ester Group via Ring-Opening Metathesis Polymerization
Novel ester group functionalized cyclic olefin polymers (COPs) with high glass transition temperature, high transparency, good mechanical performance and excellent film forming ability have been achieved in this work via efficient ring-opening metathesis copolymerization of exo-1,4,4a,9,9a,10-hexahydro-9,10(1′,2′)-benzeno-l,4-methanoanthracene (HBM) and comonomers (5-norbornene-2-yl methylaceta...
متن کاملSynthesis of functionalizable and degradable polymers by ring-opening metathesis polymerization.
A valuable approach for creating synthetic polymers is the ring-opening metathesis polymerization (ROMP). Welldefined metal carbene catalysts have been devised that afford control over the polymer chain length and architecture. In addition, ruthenium carbene initiators have been developed with excellent air stability and functional group tolerance. These catalysts enable the synthesis of polyme...
