摘要

The dynamic behavior of diethylene glycol bis(allyl carbonate) (CR-39)/acrylic acid (AA) copolymers was evaluated by C-13 high-resolution solid-state nuclear magnetic resonance (NMR). The NMR data showed that the copolymerization of CR-39 and AA generated copolymers with different molecular behaviors as a function of AA content, which promoted changes in the crosslinking of CR-39 chains and in the intramolecular forces. The copolymerization process influenced the sequence distribution and domain formation of the monomers, which is a consequence of the dispersion of comonomers along the macromolecular chains.
