Synthesis of poly(decahydro-2-naphthyl methacrylate)s with different geometric structures and effects of side-group dynamics on polymer properties investigated by thermal and dynamic mechanical analyses and DFT calculations

We prepared the geometric isomers of decahydro-2-naphthols as the source materials for the synthesis of poly(decahydro-2-naphthyl methacrylate)s [poly(DNMA)-I, -II, -III, and -IV] including alicyclic ester groups with different geometric structures. The geometry and conformational dynamics of the decahydro-2-naphthyl moieties were investigated by NMR spectroscopy and DFT calculations. We synthesized each isomer of the methacrylic monomers, polymerized them, and investigated the optical, thermal, and mechanical properties of poly(DNMA)s with different isomer compositions. The Tg values of the poly(DNMA)s were in the following order: 139.3 C for poly(DNMA)-II 3/g, 1.489, and 42-44, respectively.
