A polyethylene composition having increased environmental stress crack resistance (ESCR) is comprised of a polymer blend of a high density polyethylene (HDPE) and a polycarbonate-siloxane copolymer. The polycarbonate-siloxane copolymer is present in the polymer blend in an amount of from 0.5 wt. % to 15 wt. % by total weight of the polymer blend. In a method of forming a polyethylene composition having increased ESCR, a HDPE is modified by combining the HDPE with a polycarbonate-siloxane copolymer in a polymer blend, the polycarbonate-siloxane copolymer being present in an amount of from 0.5 wt. % to 15 wt. % by total weight of the polymer blend. The polymer blend can be formed into an article of manufacture, such as a bottle cap.
