Abstract
The structure of n-butyl acrylate–styrene block and gradient copolymers of various compositions is studied in detail, and their glass transition temperatures are determined. Influence of the architecture of copolymer macromolecules on the glass transition temperature is considered. Histograms of the size distribution of phases are constructed, and the density distribution of domains over the cross section of the dispersed phase is estimated. Schematic representations of the structure of the block and gradient copolymers are proposed, and their features are analyzed.
