FIELD: chemistry of polymers.
SUBSTANCE: invention relates to preparing shock-resistant antifreeze polypropylene compositions. The shock-resistant antifreeze composition comprises the following components, wt.-%: isotactic polypropylene, 77.0-85.7; elastomer, 14.0-18.0, wherein poly-1-octene with the intrinsic viscosity value in the range from 4.0 to 12.0 dl/g is used; thermostabilizing agent, 0.1-0.5, and special additives, the balance. Shock-resistant antifreeze polypropylene composition is characterized by improved melt fluidity indices that providing the improved processing capacity. Invention can be used in automobile manufacture, building and light industry for production of articles of technical designation exploited at reduced temperatures.
EFFECT: improved and valuable technical properties of composition.
