Abstract: A method of the selection, modification of existing, and/or creation of polyester based polymer materials, which provide improved response to the application of local shear and/or extensional deformation inside the polyester based polymer melt in injection stretch blow molding, is disclosed. A method for manufacturing a polymer article is also provided including injecting a molten polyester based polymer in a preform mold for converting it in a preform while applying shear and/or extensional deformation on the polyester based polymer melt. Applying shear and/or extensional deformation on the polyester based polymer melt includes modifying the flow path of the molten polymer as a function of local pressure profile over at least part of the flow path. The local pressure profile is determined as a function of optimized response of the polyester based polymer melt to the applied local shear and/or extensional deformation over at least said part of the flow path.

Abstract: A method enabling the selection, modification and/or creation of polymer materials which can provide improved response to the application of local shear and/or extensional deformation inside the polymer melt in manufacturing technologies including injection molding, injection stretch blow molding, direct injection, extrusion blow molding, sheet extrusion, thermoforming, etc., is provided. A method for manufacturing a polymer article includes injecting or extruding molten polypropylene, polyethylene or polyester based polymer for converting it into semi-final shape while applying shear and/or extensional deformation on the polymer melt. Applying shear and/or extensional deformation on the polymer melt includes selectively modifying the flow path of the molten semi-crystallizable polymer as a function of local pressure profile over at least part of the flow path.
