Impact-modified polymer

{
  "id": "MLC-T-CHM-005722",
  "term": "Impact-modified polymer",
  "field": "Chemistry",
  "definition": "A polymer material whose resistance to fracture under sudden, high-velocity impact has been enhanced by the inclusion of a second, elastomeric phase. This is typically achieved by blending a rigid polymer matrix, such as polystyrene or polypropylene, with a rubbery polymer that forms dispersed domains within the matrix. High-impact polystyrene (HIPS), which incorporates polybutadiene rubber, is a widely produced example of this material class.",
