Effect of chain flexibility in the network structure on the viscoelasticity of epoxy thermosets

In this paper a detailed study in investigating the effect of the chain flexibility in epoxy-amine crosslinked network is done. In order to introduce flexibility into the crosslinked network a homologous series of four aliphatic diamine curing agents varying only in the chain length and having a constant functionality (f?=?4) is taken and cured...
