FIELD: physics.
SUBSTANCE: invention refers to size control method for disperse particles in thermoplastic elastomer composition. Disperse particle size control method includes mixing in melt of the following: (A) halogenated isobutylene elastomer, (B) polyamide, (C) dispersion supplement, and (D) traditional additives. Resulting mixture is subjected to dynamic vulcanization thus forming dynamically vulcanized resin mix; halogenated isobutylene elastomer is dispersed in polyamide matrix at volume-averaged diameter of dispersion particles Dv from 0.01 to 2.5 μm.
EFFECT: thermoplastic elastomer composition with controllable size of disperse elastomer particles and improved durability and impermeability.
