Multi-layered, core and shell particles are used to rotationally mold articles. The core and shell materials may be thermoplastic polymers, the difference between the core and the shell will be at leat 0.5 melt index units, optionally, the core and shell may also differ by at least about 1 DEG CTm. The core and shell particles produce a rotationally molded article with generally an outer layer (of the molded article) that fuses more easily, and an inner layer that may provide superior toughness. |
