Used primarily as a comonomer in the production of polyethylene, especially high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE), to improve strength, flexibility, and impact resistance. It modifies the polymer structure by introducing short branches, enhancing the material’s performance in films, containers, and pipes. Also employed in the synthesis of alcohols, plasticizers, and surfactants through hydroformylation and other chemical processes. Its reactivity makes it valuable in organic synthesis and industrial chemistry for creating specialty chemicals.
