impact-modified polymer 

https://doi.org/10.1351/goldbook.IT07175
Polymeric material whose impact resistance and toughness have been increased by the incorporation of phase microdomains of a rubbery material.
Note:
An example is the incorporation of soft polybutadiene domains into glassy polystyrene to produce high-impact polystyrene.
