AbstractThe stereocomplexation of atactic poly(methyl methacrylate) (a-PMMA) films after isolated from acetone,benzene, acid chloroform solution, respectively, was studied by Fourier transformation infrared (FTIR). The results of spectra showed that the stereo-complex was formed for the films cast from acetone and benzene solutions with the appearance of the characteristic bands far the stereo-complex. The population of trans-trans conformers for the i- and s-sequences increased and the side chain preferred to its energetically optimized conformation during the formation of stereocomplex. The stereocomplexes may be formed by the interactions between the i-and s-sequences in the same molecular chain. During the annealing process the self-aggregation of s-sequences played a role in the aggregation process of stereocomplex, which was a function of annealing temperature and annealing time.
