摘要：

In this work, a straightforward method of vulcanizing acrylate rubber (AR) was explored via the introduction of in situ coordination crosslinking. An inorganic metal salt, copper sulfate (CuSO4), was mechanically mixed with AR and heat pressed to prepare a novel crosslinkable AR/CuSO4 composite. The determination of the coordination bonding between the ester groups of AR and copper (II) ions was performed with Fourier transform infrared spectroscopy based on the red shifts of the ester group absorption bands and the disappearance of the coordinated sulfate absorption bands, as well as by electron spin resonance based on the changes in the g-factor of copper (II). The crosslinking procedure of the composite was investigated through dynamic mechanical analysis. In addition, the extent of the crosslinking of the AR/CuSO4 composites was evaluated by observing the swelling behaviors. Scanning electron microscopy was used to investigate the morphology of the composite. The vulcanizates exhibited improved physical properties with high elongation at break due to exchange reaction between the ester groups of AR and CuSO4.
