Abstract: Extrusion blow molded (EBM) articles comprising a polyester having a dicarboxylic acid component and a glycol component. The dicarboxlyic acid component comprises at least 90 mole % terephthalic acid residues. The glycol component comprises at least 75 mole % ethylene glycol residues and 15 to 25 mole % residues of a difunctional glycol such as, for example, 1,4- cyclohexanedimethanol. Such EMB articles can exhibit reduced haze, reduced sharkskin, and/or increased compatibility in PET recycling.

Abstract: Blends of polycarbonate and copolyester that are capable of being extrusion blow-molded are described. The blends preferably comprise (I) about 1 to 99% by weight of a linear or branched polycarbonate and (II) about 1 to 99% by weight of a mixture of (i) about 40 to 100% by weight of a first copolyester and (ii) about 0 to 60% by weight of a second copolyester. The first copolyester preferably comprises (A) diacid residues comprising terephthalic acid residues, (B) diol residues comprising about 45 to 75 mole percent of 1,4-cyclohexanedimethanol (CHDM) residues and about 25 to 55 mole percent of ethylene glycol residues, and (C) about 0.05 to 1.0 mole percent of the residue of a trifunctional monomer. The optional second copolyester preferably comprises (A) diacid residues comprising terephthalic acid residues and (B) diol residues comprising about 52 to 90 mole percent of CHDM residues and about 10 to 48 mole percent of ethylene glycol residues. Preferably, the average amount of CHDM residues in the copolyester mixture II ranges from 52 to 75 mole percent. It has been surprisingly found that the presence of the trifunctional residues in the first copolyester can impart sufficient melt strength for the blends to be extrusion blow-molded. Containers and shaped articles made from the blends as well as a method of making the articles are also described.

Abstract: A multi-layer electrostatic dissipative structure that is clear to translucent, washable and thermoformable comprises at least one outer layer and a core layer. Preferably, two outer layers are utilized with the core layer sandwiched therebetween. The outer layers are a blend of amorphous or semi-crystalline copolyester and an electrostatic dissipative polymer in an amount sufficient to impart a surface resistivity of about 10 to 10 Ohms/sq. The core layer is a polymer having a haze value of less than five percent, preferably amorphous or semi-crystalline copolyester. The multi-layer structure may additionally have a tie layer between the core layer and each of the outer layers.
