In one embodiment, the present invention is a polymeric composition, in pellet form, which comprises a vinyldene chloride interpolymer, and a friction reducing polymer (FRP) in an amount of from about 0. 1 to about 40 weight percent, said weight percent being based on the total weight of the polymeric composition. The FRP is selected to selected to lower the frictional coefficient and the mechanical energy to extrude of the polymeric composition. In another embodiment, the present invention is a polymeric composition, in either power or pellet form, possessing improved extrudability, composition comprises a vinylidene chloride interpolymer in an amount of from about 55 to about 99. 85 weight percent, a FRP in an amount from about 0. 1 to about 40 weight percent, and a salt of an acid in an amount of between about 0.
