Chemical heterogeneity of copolymers and its characterization

Polimery 2001, No 11-12, 761


DOI: dx.doi.org/10.14314/polimery.2001.761


Summary

The heterogeneity of copolymers in chemical composition is overviewed qualitatively. The following topics are discussed: the non-uniformity of copolymers and its description; the heterogeneity of statistical and block copolymers; the effect of chemical heterogeneity on the properties of copolymers; the methods used to characterize chemically heterogeneous copolymers; size-exclusion chromatography (SEC) of copolymers involving concentration and composition detection; SEC with on-line concentration and light-scattering detection; and the calculation of the distribution functions of chemically heterogeneous copolymers based on the operating parameters of synthesis.


Keywords: statistical copolymers, block and graft copolymers, chemical heterogeneity, chemical composition distribution, methods for characterization of chemically heterogeneous copolymers
