Abstract: Disclosed is a process for preparation of a propylene-based polymer composition involving the steps of: (a) mixing a propylene-based polymer and a peroxydicarbonate in a mixing device, wherein the mixing takes place at a temperature of ≤30° C., wherein the peroxydicarbonate is introduced into the mixing process in a dry form; (b) keeping the mixed composition at a temperature of ≤30° C.; (c) feeding the mixed composition into a melt extruder; (d) homogenizing the mixed composition at a temperature where the propylene-based polymer is in solid state during an average residence time of ≥6.0 and ≤30.0 seconds; (e) further homogenizing the mixed composition at a temperature at which the propylene-based polymer is in the molten state; and (f) extruding the homogenized material from a die outlet of the melt extruder followed by cooling and solidification; wherein the steps (a) through (f) are conducted in that order.

Abstract: An anisotropic polycarbonate foam is disclosed. The polycarbonate foam has a low open cell content, and has improved mechanical properties as specified herein. A process for making an anisotropic polycarbonate foam, can comprise: melting a polycarbonate in an extruder to obtain a molten formulation; injecting a blowing agent into the molten formulation; mixing the molten formulation to obtain a single phase mixture; and extruding the single phase mixture through a die to obtain the anisotropic polycarbonate foam.

Abstract: The present invention relates to a thermoplastic polyester copolymer comprising 50-1000 ppm with regard to the total weight of the thermoplastic polyester copolymer of moieties derived from an alcohol having ≥3 hydroxy moieties. Such thermoplastic polyester copolymer allows for the production of high-quality foamed articles, whilst reducing the need for additives that are to be incorporated in the copolymer.
