Sažetak
The results of the studies of the conformational structure
of stereoregular PMMA obtained by means of infrared spectroscopy,
combined with NMR spectroscopic studies of the kinetics of the aggregation of s-PMMA, are described. It was found that both the aggregation of s-PMMA and PMMA stereocomplex formation
lead to the generation of double helices with a large number of monomer units per turn, and that such heli ces also exist in all three crystalline forms of stereoregular PMMA (i-PMMA, s-PMMA, stereocomplex) in the solid state. Interactions leading to the formation of the stereocomplex can enforce this structure even in s-PMMA chains with not too high stereoregularity.
