Abstract

A simple method for the two-stage synthesis in one reactor on one catalyst of heterophase thermoplastic
elastomers based on isotactic polypropylene (PP) and an ethylene-propylene copolymer or an ethylene-
propylene-1,4-hexadiene terpolymer is developed. The obtained materials, depending on the composition,
have good elastomeric properties or behave like thermoplastics. Polymers in which ethylene units form
long sequences have the best set of basic characteristics: high values of the elastic modulus, strength, and
elongation at a break, as well as a low residual deformation.
