A method comprising preparing a styrenic polymer composition, melting the styrenic polymer composition to form a molten polymer, injecting the molten polymer into a mold cavity to form a preform, heating the preform to produce a heated preform, and expanding the heated preform to form an article. A method comprising substituting a styrenic polymer composition comprising from 0 wt. % to 6.5 wt. % plasticizer and equal to or greater than 2.5 wt. % elastomer for polyethylene terephthalate in an injection stretch blow molding process, wherein the wt. % is based on the total weight of the polymeric composition. A method comprising preparing a preform from a styrenic polymer composition, subjecting the preform to one or more heating elements, and rapidly heating the preform to produce a heated preform.
