FIELD: chemistry.
SUBSTANCE: invention relates to methods of modifying layered nanosilicates meant for preparing polymer nanocomposites. The modification method involves dispersing smectite clay into 1M aqueous sodium salt solution, separating impurities, treating the obtained product with a compound containing organic cations the amount of which is determined using a given formula, extracting modified clay, washing and drying at temperature 100-120°C.
EFFECT: high quality of modified nanosilicates and low power consumption of the process.
