ABSTRACT This invention relates to an improved process of blow molding, and to improved compositions useful for blow molding, wherein articles are blow molded from compositions formed from thermoplastic polymeric material, a fluorinated olefinic polymer or copolymer and, optionally, an elastomeric impact modifier. The presence of the fluorinated olefinic polymer or copolymer in the blow molding composition increases the melt strength of the thermoplastic polymeric material. This makes the thermoplastic polymeric material more useful for blow molding because a parison of greater size and weight can be formed from the polymeric material because of its increased melt strength. 38,077-F
