A shaped article comprising a polymer-based resin derived from cellulose, wherein the polymer-based resin has an HDT of at least 95&#xb0; C., a bio-derived content of at least 20 wt %, a notched izod impact strength of greater than 80 J/m and at least one of the following properties chosen from: flexural modulus of greater than 1900 MPa; a spiral flow length or at least 3.0 cm; a flex creep deflection of less than 12 mm; a transmission of at least 70%; a &#x394;E value of less than 25; or an L* color of at least 85.

Polymer-based resin compositions derived from cellulose and articles made using these compositions

An injection molded article comprising a thin-walled body portion formed from a polymer-based resin derived from cellulose, wherein the thin-walled body portion comprises:

Described as one aspect of the invention are extrusion blow molded articles comprising at least one polyester which comprises:

Copolyesters and blends with improved recyclability, processes for their manufacture, and articles prepared therefrom

Extrusion blow molded (EBM) articles comprising a polyester having a dicarboxylic acid component and a glycol component. The dicarboxylic 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 EBM articles can exhibit reduced haze, reduced sharkskin, and/or increased compatibility in PET recycling.

Extrusion blow molded articles

Extrusion profile 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 extrusion profile articles can exhibit reduced haze, reduced sharkskin, and/or increased compatibility in PET recycling.

Extrusion profile articles

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&#xb0; C. to 130&#xb0; 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&#xb0; C. greater than the glass transition temperature (Tg) of the polymeric material.

Plastic baby bottles, other blow molded articles, and processes for their manufacture

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 &#x2212;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.
