Zusammenfassung:	Rotational molding processes for producing hollow articles include the steps of: a) filling a mold with a polymer composition comprising: i) an organic polymer; and ii) a rotational molding densification accelerator (RMDA) selected from the group consisting of alkoxylated fatty alcohols, alkoxylated fatty esters, alkoxylated fatty amines, alkoxylated fatty amides, and combinations thereof; b) rotating the mold around at least one axis while heating the mold in an oven, thereby fusing the composition and spreading it to the walls of the mold; c) cooling the mold; and d) opening the mold; and e) removing the hollow article from the mold. The rotational molding processes using such polymer composition results in faster densification, which allows for reduction in overall cycle times for making the hollow articles.
