Evaluation of the diethylene glycol bis(allyl carbonate)/acrylic acid copolymer behavior by solid-state 13C-NMR



The dynamic behavior of diethylene glycol bis(allyl carbonate) (CR-39)/acrylic acid (AA) copolymers was evaluated by 13C 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. © 2005 Wiley Periodicals, Inc.
