摘要： Disclosed are polymer compositions having high transparency and low haze comprising immiscible blends of one or more thermoplastic polymers selected from polyesters, polycarbonates, and polyarylates, and a copolyamide or a transamidized, homogeneous blend of a least two polyamides. The components of the immiscible blend which have refractive indices which differ by about 0.006 to about -0.0006. The small difference in the refractive indices enable the incorporation of regrind into the polymer composition to produce transparent shaped articles. The blends of the present invention are useful in producing shaped articles such as, for example, sheeting, films, tubes, bottles, preforms and profiles. These articles may have one or more layers and can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties. Metal catalysts can be incorporated into the compositions to produce oxygen-scavenging compositions.

摘要： 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.

摘要： The invention is generally directed to baby bottles and other articles produced by blow molding from polymeric materials having glass transition temperatures ranging from 100°C to 130°C, as well as to processes for producing them. These articles can be exposed to boiling water and can be produced by using a suitable combination of a stretch ratio of less than 3 and a preform temperature at least 20°C greater than the glass transition temperature (Tg) of the polymeric material.

摘要： Disclosed is a process for the preparation of shaped articles such as, for example, sheeting, films, tubes, bottles, preforms and profiles, having high transparency and low haze, and comprising immiscible blends of at least one polyester comprising 2,2,4,4-tetramethyl-l ,3-cyclobutanediol, and a copolyamide or a transamidized, homogeneous blend of a least two polyamides. The components of the immiscible blend have refractive indices which differ by about 0.006 to about -0.0006. The small difference in the refractive indices enable the incorporation of regrind into the polymer composition to produce transparent shaped articles. These articles may have one or more layers and can exhibit improved excellent barrier properties and good melt processability while retaining excellent mechanical properties. Metal catalysts can be incorporated into the compositions to produce shaped articles having oxygen-scavenging properties.

摘要： Disclosed is a biaxially-oriented polyester film produced from a polyester comprising: (1) diacid residues comprising between about 95 and about 100 mole percent of terephthalic acid residues; (2) diol residues comprising between about 95 and about 100 mole percent of 1,4-cyclohexanedimethanol residues; and (3) about 0.5 to about 5 mole percent of another dicarboxylic acid or diol residue, wherein the polyester comprises a total of 100 mole percent diacid residues and a total of 100 mole percent diol residues. In one embodiment, the biaxially-oriented film has a thickness of 70 to 150 microns (3-5 mils). In another embodiment, the biaxially-oriented film undergoes not more than 3% shrinkage when immersed for 10 seconds in a solder bath preheated to 260°C. The film can be made by stretching an essentially amorphous cast-film of thickness between about 450-1800 micron (18-70 mil) at a ratio from about 2.5x2.5 to 3.5x3.5 while being held at a temperature between 90°C and 130°C, and heat-setting the stretched film at an actual film temperature of from 260°C to Tm, where Tm is the melting point of the polyester as measured by differential scanning calorimetry (DSC), while maintaining the dimensions of the stretched film.
