13C NMR solid state characterization of diethylene glycol bis(allyl carbonate) and acrylic acid copolymers

The evaluation of the copolymer behavior formed by diethylene glycol bis(allyl carbonate) and acrylic acid was chosen to be done applying 13C high-resolution solid state nuclear magnetic resonance to better understand the dynamical behavior. The NMR data showed that the copolymerization of CR-39 and AA, formed copolymers with different molecular behavior as a function of AA quantity, which promotes change in the cross linking of CR-39 chains. The copolymerization process also influenced the distribution form and proportion of the domains formed, which is a consequence of the comonomer dispersion along the chains. (author)
