Ring-opening metathesis polymerization (ROMP) of N-cycloalkyl-7-oxanorbornene dicarboximides by well-defined ruthenium initiators

First FT-Raman and 1H NMR comparative investigations in ring opening metathesis polymerization

“…This conclusion perfectly correlates with our NMR data, as fully illustrated by Fig. 4 and Table 2, and is in total agreement with the ample literature information on the preferred formation of the trans isomer in ROMP initiated by Grubbs' 1st generation catalyst [1,43].…”

Chain Elongation Influence in Copolymerization with Different Diesters of Norbornene 2,3-Dicarboxylic Acid Monomers via ROMP under Air Atmosphere

“…The literature shows that studies on 5-norbornene-2,3-dicarboxylic ester derivatives are important for the development of new materials, which can be verified by the relevant number of recent publications. 8,[10][11][12][13] In contrast, in this study, the use of air atmosphere makes the means more robust, being a new contribution to science.…”

“…Later, Vargas et al 8 studied the copolymerization of aminomonomers with NBE and, more recently, Yang et al 6 presented the shape memory study of a copolymer of NBE cyano derivative with NBE e-caprolactone derivative. Part of these studies were conducted because when NBE is copolymerized with other monomers with hydrophilic characteristics, it may form an important copolymer with amphiphilic properties, containing hydrophobic and hydrophilic blocks.…”

“…5-Norbornene-2,3-dicarboxylic acid and its esters are vastly used as monomers in ROMP reactions. 7,8,[10][11][12][13] NBE-(COOCH 3 ) 2 and NBE-(COOCH 2 CH 3 ) 2 are examples of 5-norbornene-2,3-dicarboxylic derived acid esters presented in the literature 8,11,12 in studies of polymerization via metathesis using different metathesis catalysts. Demel et al 11 presented an interesting study on the influence of Grubbs' catalysts in the ROMP of (NBE-(COOCH 2 CH 3 ) 2 ), revealing superior activity of the second Grubbs' catalyst and intermediary activity of the first generation catalysts.…”

Synthesis of high‐Tg polymers via ROMP of oxanorbornene dicarboximides with halogen groups

“…• C [4,[7][8][9][10][11]. The membranes prepared from polyoxanorbornenes with lateral imide groups exhibit high permselectivity for the separation of hydrogen from nitrogen, carbon monoxide, methane, and ethylene [12][13][14].…”
