## Abstract The surface microstructure of the cast films of syndiotactic and stereocomplex poly(methyl methacrylate)s (PMMA) was studied by the attenuated total reflection IR (IR/ATR) method. For comparison, the bulk structure was analyzed by transmission IR spectroscopy. For the syndiotactic PMMA,
Three poly(methyl methacrylates) (PMMA) with a racemic fraction ranging from 0.25 to 0.91 have been adsorbed from a chloroform solution on β₯-alumina and studied by diffuse reflectance infrared spectroscopy (DRIFT) and solid-state 13 C NMR spectroscopy. From DRIFT spectra, it is seen that the fractio
