Synthesis, morphology, and thermal stability of nanoporous cyanate ester resins obtained upon controlled monomer conversion

Acceleration effect of ionic liquids on polycyclotrimerization of dicyanate esters

“…In the first stage the mixtures of DCBE monomer with different amounts of ionic liquid [OMIm] [BF 4 ] were heated at 150°C for 6 h. In the presence of a catalyst, one such curing step permitted to attain a gel point [30]. Figure 1a exhibits .…”

Systematic study on highly efficient Thermal Synergistic Polymerization effect between alicyclic imide moiety and phthalonitrile: Scope, Properties and Mechanism

“…As we know, high performance resins based on these reactive groups of cyanate ester [13], maleimide [14], phenylethynyl [15][16] and benzocyclobutene [17] have received much attention in the past decades, in the view of scientific or industrial value. This is due to a fact that these resins cure via an addition reaction with no volatile by-products evolved during the processing stage.…”

Nanoporous Cyanate Ester Resins: Structure-Gas Transport Property Relationships

“…Lately, we have developed a simple method for generating nanoporous film materials based on CERs by varying the rate and degree of completion of curing associated with the polycyclotrimerization of dicyanate monomer. A series of nanoporous CER films obtained by such incomplete conversion technique were thus synthesized [ 22 ]. We have also implemented a chemically induced phase separation route toward the formation of nanoporous pure CER networks by using inert high-boiling temperature porogens, e.g., dimethyl- and dibutyl phthalates, during network formation, followed by their quantitative removal [ 23 ].…”
