The Phillips catalyst refers to a specific type of catalyst used in the polymerization of ethylene to produce polyethylene, developed by a team of researchers at Phillips Petroleum Company in the 1950s. This catalyst is a chromium-based catalyst, typically chromium oxide, supported on silica. The Phillips catalyst is notable for its ability to produce low-density polyethylene (LDPE) and has significant industrial importance due to its efficiency in converting ethylene into high molecular weight polyethylene.
