The present project is based on the synthesis of new essentially amino-ended copoly(ether sulphone)swhich are characterized by the presence of rigid biphenyl units in the main chain. All the compoundshave been fully characterized by (1H and 13C) NMR, FTIR, and MALDI-TOF MS techniques. Completeassignments of the 1H and 13C NMR spectra have been accomplished by comparison with modelcompounds and literature data. The thermal properties of the copolymers were studied by differentialscanning calorimetry (DSC). The glass transition temperature of the copolymers increases as increasingthe molar composition of ethere sulphone units containing biphenyl moiety. The copolymers synthesizedmight find application as reactive toughening agents for multifunctional epoxy resins when high thermalproperties are a requirement

Abstract
The present project is based on the synthesis of new essentially amino-ended copoly(ether sulphone)swhich are characterized by the presence of rigid biphenyl units in the main chain. All the compoundshave been fully characterized by (1H and 13C) NMR, FTIR, and MALDI-TOF MS techniques. Completeassignments of the 1H and 13C NMR spectra have been accomplished by comparison with modelcompounds and literature data. The thermal properties of the copolymers were studied by differentialscanning calorimetry (DSC). The glass transition temperature of the copolymers increases as increasingthe molar composition of ethere sulphone units containing biphenyl moiety. The copolymers synthesizedmight find application as reactive toughening agents for multifunctional epoxy resins when high thermalproperties are a requirementFile | Dimensione | Formato | |
