<p>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.</p> |
