Title:
POLYESTER MELT-PHASE COMPOSITIONS HAVING IMPROVED THERMO-OXIDATIVE STABILITY, AND METHODS OF MAKING AND USING THEM
Document Type and Number:
WIPO Patent Application WO/2010/033161
Kind Code:
A3
Abstract:
Polyester compositions are disclosed that include a melt-phase polyethylene terephthalate polyester having incorporated therein residues of a monomer having two or more fused aromatic rings, and that also include aluminum, and optionally an alkali metal or an alkaline earth metal. Also disclosed are articles that include the disclosed polyester compositions, and processes for producing such polyester compositions, that include the steps of forming a mixture comprising ethylene glycol, at least one acid chosen from terephthalic acid and derivatives of terephthalic acid, and a monomer having two or more fused aromatic rings; and reacting the mixture in the presence of aluminum, and optionally an alkali metal or an alkaline earth metal, to obtain the melt-phase polyethylene terephthalate polyester.
