Crosslinking chemistry for high-performance polymer networks

Abstract: A new thermally reactive monomer has been designed and synthesized that brings novel crosslinking chemistry to high-performance polymers. This monomer (XTA) is a derivative of terephthalic acid and was based on the thermal chemistry of benzocyclobutene. Various model compounds have been synthesized to investigate substituent effects on benzocyclobutene reactivity. Irreversible reaction exotherms around 350°C were observed in these model compounds using differential scanning calorimetry. Based on these studies,… Show more

“…This could be attributed to the resin type, in which a rubber compound was added to an acrylic resin to produce a resin with high strength, which is called a high‐impact acrylic resin . Moreover, this type of resin is made with a high degree of homogeneity that prevents changes within this material, as the bonds between the molecules are more stable under higher temperatures and pressures . Heat treating over a longer time and increased pressure also increases cross‐linking.…”

“…The type of bonds among the molecules of this type of acrylic resin is also more stable under higher temperatures. (30) Also the type of acrylic used in present study contains a cross linking agent which provides a sufficient number of bridges between linear macromolecules to form a three-dimensional network that increases the strength and rigidity of the resin. (29) The results of this research showed no significant difference in transverse strength test between the means of the samples of all the test groups; autoclave processing long (AL), autoclave processing short (AS) and water bath )W( group.…”

“…The thermal annealing at 350 °C removed the PEG segment according to the TGA analysis as shown in Supporting Information, Figure S2. At this temperature, close to the polymer melting temperature, BCB dimerization to crosslink polyarylamide chains will occur simultaneously …”
