Abstract
Ionomers of poly(methyl methacrylate-co-methacrylic acid) crosslinked by titanium (IV) (Ti4+) and zirconium (IV) (Zr4+) ions were prepared, and their structures, optical absorption and viscoelastic properties were investigated. IR measurement revealed that tetravalent metal ions were coordinated by -COO- groups of deprotonated methacrylic acid and functioned as crosslinkers. The coordination of -COO- to the Ti4+ especially brought about strong UV absorption below 360-370 nm owing to charge transfer. Dynamic mechanical thermal analysis (DMTA) showed storage modulus (E′) below glass transition temperature (Tg) and a peak temperature of tan δ for every ionomer not to increase regardless of metal ion content. This was attributed to residual alcohols. E′ above Tg increased with metal ions content, and DMTA for every ionomer was measured up to 350°C. Crosslinking by tetravalent metal ions thus greatly improves heat resistance of host polymers.
