Abstract: Manufacturing of polyester based expanded materials made mostly of pre-cleaned and compounded post-consumer polyester by increasing the intrinsic viscosity (IV) during an extrusion process is described. By careful selection of processing conditions and parameters, it is possible to obtain low density polyester foam material with good cellular structure and under stable processing conditions.

Abstract: An extrusion expansion of low molecular weight polyalkylene terephthalates having an IV of below 1.0 dl/g to produce gas-charged beads is disclosed in this invention. The process is comprised of an extrusion expanding of the resins and an underwater pelletizing of the melt threads. The obtained beads show a composite structure and are characterized by an IV of 0.69dl/g or more and a melt viscosity .eta.0 of higher than 300 Pa.s.

Abstract: The composition and the preparation of a chain-extending concentrate for production of foamed cellular materials of aromatic polyesters is disclosed in this invention. The chain-extending concentrate is comprised of an ethylene-acrylate copolymer, a high-temperature thermoplastic and a multifunctional compound. The preparation process consists of two steps: 1) Mixing and melt blending the multifunctional compound and the HT thermoplastic resin into the matrix of the ethylene-acrylate copolymer in an internal mixer and 2) extrusion of the mixture at a temperature below the melting point or reaction temperature of the multifunctional compound.
