Abstract: A styrenic polymer characterized by a z-average molecular weight of from about 339 kDa to about 520 kDa; a molecular weight distribution of from about 2.5 to about 5.0; a melt strength of from about 0.010 N to about 0.018 N and a melt A method of preparing a styrenic polymer comprising contacting a styrenic monomer, an optional comonomer and an optional initiator to a plurality of temperature environments wherein the difference in temperature between the first environment and the last environment is greater than about 30° C. to form the styrenic polymer; and recovering the styrenic polymer.
