CA 2737532

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 titanium. 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 titanium to obtain the melt-phase polyethylene terephthalate polyester.

La présente invention a pour objet des compositions de polyester qui comprennent un polyester de polyéthylène téréphtalate en phase fondue dans lequel sont incorporés des résidus dun monomère ayant deux cycles aromatiques condensés ou plus, et qui comprennent également du titane. La présente invention a également pour objet des articles qui comprennent les compositions de polyester décrites, et des procédés pour la production de telles compositions de polyester, qui comprennent les étapes consistant à former un mélange comprenant de léthylène glycol, au moins un acide choisi parmi lacide téréphtalique et les dérivés de lacide téréphtalique, et un monomère ayant deux cycles aromatiques condensés ou plus ; et à faire réagir le mélange en présence de titane pour obtenir le polyester de polyéthylène téréphtalate en phase fondue.
