Title (EN) COPOLYESTERS OF TEREPHTHALIC ACID AND 1,4-CYCLOHEXANEDIMETHANOL HAVING IMPROVED MELT STABILITY
(FR) COPOLYESTERS D'ACIDE TEREPHTALIQUE ET 1,4-CYCLOHEXANEDIMETHANOL PRESENTANT UNE STABILITE EN FUSION AMELIOREE
Abstract:
(EN) Disclosed are copolyesters of terephthalic acid and 1,4-cyclohexanedimethanol containing selected phosphites or phosphonites which improve molecular weight retention after exposure to melt temperatures. In the phosphite or phosphonite, at least one of the P-O bonds is attached to an aryl radical. The compositions are useful in clear injection molding applications.
(FR) Copolyester d'acide téréphtalique et 1,4-cyclohexanediméthanol contenant des phosphites ou des phosphonites sélectionnés, lesquels améliorent la rétention de masse moléculaire après exposition à des températures de fusion. Dans le phosphite ou le phosphonite, au moins une des liaisons P-O est fixée à un radical aryle. Les compositions sont utiles dans des applications de moulage par injection transparentes.
