The gradient intramolecular inhomogeneity was established for copolyme
rs of styrene with methacrylic and acrylic acids, acrylonitrile, acryl
amide, and of vinyl acetate with 2-methyl-5-vinylpyridine prepared by
homogeneous radical copolymerization carried out up to 5 - 7% conversi
ons. The intramolecular inhomogeneity, which is characterized by the m
onotonic change of composition along the copolymer chain, results from
molecular mass dependence on selective sorption of the monomers.
