Abstract
Research of structure and composition of styrene-butadiene copolymer studied in the paper on the basis of modeling of copolymerization process by the Monte Carlo method. Distribution of free-radical copolymerization product on the size and composition is built. The effect of feeding mode of chain transfer agent (tert-dodecylmercaptan) to modify of the microstructure of the product has been analized. Three-point feeding mode of chain transfer agent helps to narrow the range of changes microheterogeneity index compared to the two-point feeding mode.
