## Abstract A comprehensive structural characterisation of cross‐linked insoluble poly(amidoamine) (PAA) networks was performed by high‐resolution magic angle spinning (HRMAS) NMR spectroscopy. Model samples with 20%, 40% and 80% cross‐linking degrees were prepared and the best conditions to obtain
The positive SIMS spectrum of poly(methyl methacrylate) (PMMA) has been obtained with a mass resolution in excess of 8000 and all the components assigned up to m/z 200 based on accurate mass measurements. Aspects of the interpretation of the spectrum, previously based on quadrupole SIMS data from a
Samples of Nylon G/poly(propylene oxide), with poly(propy1ene oxide) (PPO) content varying up to 35%, have been examined using thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and nuclear magnetic resonance (NMR) carbon-13 at solidstate. Carbon-13 spectra were measured by c
