Abstract

Crosslinked structures of a resin had a great influence on its properties. Studying the effect of a crosslinked network on resin properties will benefit to design and prepare a new resin with good performances. A series of alkyne group-capped oligomers were designed and well characterized. The corresponding crosslinked polytriazoles with different network grids were obtained when multifunctional azide monomer was used as a crosslinking agent. The glass transition temperature (Tg) of the crosslinked polytriazoles was measured by Differential Scanning Calorimetry. The results showed networks with a small grid size would exihibit high Tgs. The relationship between Tg and the size of the network grids of the crosslinked polytriazoles was discussed. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
