caption_attribution_description: English: High Impact Polystyrene (HIPS) consists of the polystyrene backbone with polybutadiene chains branching from it in each direction.
context_page_description: Graft polymers are segmented copolymers with a linear backbone of one composite and randomly distributed branches of another composite. The picture labeled "graft polymer" shows how grafted chains of species B are covalently bonded to polymer species A. Although the side chains are structurally distinct from the main chain, the individual grafted chains may be homopolymers or copolymers.
  Graft polymers have been synthesized for many decades and are especially used as impact resistant materials, thermoplastic elastomers, compatibilizers, or emulsifiers for the preparation of stable blends or alloys. One of the more well known examples of a graft polymer is high impact polystyrene, which consists of a polystyrene backbone with polybutadiene grafted chains.
context_section_description: Graft copolymers became widely studied due to their increased number of applications due to their unique structures relative to other copolymers such as alternating, periodic, statistical, and block copolymers which generally linear chains.
  Some common applications of graft copolymers include:
  Membranes for the separation of gases or liquids
  Hydrogels
  Drug deliverers
  Thermoplastic elastomers
  Compatibilizers for polymer blends
  Polymeric emulsifiers
  Impact resistant plastics
