<p>The composition and the preparation of multifunctional high-concentrate masterbatches for production of expanded materials of aromatic polyesters are disclosed in this invention. The masterbatch is comprised of a thermoplastic wax having a vicat softening temperature not higher than 100°C and a high-percentage of a multifunctional compound, wherein the preparation is characterized by a) a low temperature process with a masterbatch temperature lower than 100°C before cooling and b) cooling without contact of the mixture with water during the whole process. The high-concentrate masterbatch can be applied in production of expanded materials of polyester.</p> |
