A new approach to periodic vinyl copolymers via combination of atom transfer radical addition (ATRA) and atom transfer radical coupling (ATRC) is reported. The two examples are methyl methacrylate (MMA) and styrene (St) periodic copolymer (P(SMMS)) and acrylonitrile (AN) and St periodic copolymer (P(SAAS)). First, two monomer sequence units (MSU) with built‐in sequence, SMMS and SAAS, are synthesized...
Periodic copolymers of ethylene and vinyl alcohol (EVA) were synthesized via acyclic diene metathesis (ADMET) polymerization of a series of structurally symmetric α,ω-diene monomers that containing two vinyl acetate (VAc) units, followed by exhaustive hydrogenation and subsequent hydrolysis. This synthetic methodology provided a new type of EVA copolymer with defined sequence and ever highest VA content...
