Graft polymer

<p>In <a href="/facts/Polymer_chemistry/wdfr6fs4">polymer chemistry</a>, graft polymers are segmented <a href="/facts/Copolymer/35D97DuV">copolymers</a> with a linear <a href="/facts/Backbone_chain/9Q3so597">backbone</a> of one <a href="/facts/Composite_material/UBysQldh">composite</a> and randomly distributed <a href="/facts/Branching_(polymer_chemistry)/KYF9YA1j">branches</a> of another composite. The picture labeled "graft polymer" shows how grafted chains of species B are <a href="/facts/Covalent_bond/EzMLf3Pz">covalently bonded</a> to polymer species A. Although the <a href="/facts/Side_chain/Lw8KPAXn">side chains</a> are structurally distinct from the main chain, the individual grafted chains may be <a href="/facts/Homopolymer/eF32E50K">homopolymers</a> or copolymers.
Graft polymers have been synthesized for many decades and are especially used as impact resistant materials, <a href="/facts/Thermoplastic_elastomer/bBGfjapB">thermoplastic elastomers</a>, <a href="/facts/Compatibilization/HNQkHDyS">compatibilizers</a>, or <a href="/facts/Emulsifier/YMSqSCuH">emulsifiers</a> for the preparation of stable blends or <a href="/facts/Alloy/I7w7WQWR">alloys</a>. One of the better-known examples of a graft polymer is a component used in <a href="/facts/High_impact_polystyrene/dfIVntty">high impact polystyrene</a>, consisting of a polystyrene backbone with <a href="/facts/Polybutadiene/RxVmrf4B">polybutadiene</a> grafted chains.
