“…A special feature of these isocyanate monomers, which they share with MAn, is that their homopolymerization is more demanding compared with their copolymerization. While the homopolymerization of VI by conventional polymerization techniques can be accompanied by a variety of side reactions due to the competing reactivity of the vinyl double bond and isocyanate group,121 TMI homopolymerization does not yield high molecular weight polymer due to the steric hindrance imposed by the α‐methyl group to the radical propagation site 122, 123. Beyer et al synthesized MVI‐ alt ‐MAn, in which the isocyanate and anhydride groups were sequentially modified with an alcohol and amine respectively ( 1 in Scheme ) 112.…”

With a span as long as the history of polymer science itself, post-polymerization modification represents a versatile platform for the preparation of diversely functionalized polymers from a single precursor. Starting with the initial efforts by Staudinger in the 1920s, many of the early developments in modern polymer science can be attributed to the utilization of post-polymerization modification reactions. The scope of post-polymerization modification has greatly expanded since the 1990s due to the development of functional group tolerant controlled/living polymerization techniques combined with the (re)discovery of highly efficient coupling chemistries that allow quantitative, chemoselective, and orthogonal functionalization of reactive polymer precursors. After some basic mechanistic considerations, this Highlight will provide an overview of the development and evolution of eight main classes of post-polymerization modification reactions.

“…Homopolymerization of vinyl isocyanate in DMF/DMAc at -55", using sodium cyanide as the initiator, produces 1-nylon homopolymers while at room temperature polymerization proceeds through the vinyl group (Overberger, 1964;Schulz and Hartmann, 1962;Schulz and Stenner, 1964). Heating of the 1-nylon polymer in DMAc, treatment with azoisobutyronitrile, or exposure to ultraviolet light produces ladder polymers (cyclopolymer).…”

“…Scheme 1.3Polymers bearing isocyanate, n-alkyl pentafluorophenyl, allyl ether, and alkyne groups that can be quantitatively modified with various reagents, but under different reaction conditions[28,51,54,65,66]. While the homopolymerization of VI by conventional polymerization techniques can be accompanied by a variety of side reactions because of the competing reactivity of the vinyl double bond and isocyanate group[62], TMI homopolymerization does not yield high-molecular-weight polymer because of the steric hinderance imposed by the α-methyl group to the radical propagation site[63,64]. A special feature of these isocyanate monomers, which they share with MAn, is that their homopolymerization is more demanding compared to their copolymerization.…”
