V. at their surface which is less than 0.25 dL/g higher than the It. V. at their center. The polyester particles may have not been solid stated. The melt processing device comprises a screw with a total length (9), L, a feed zone length (3) in the range from 0.1 SL and 0.45L, a taper angle, in the range from 0.5 degrees and 5.0 degrees and a compression ratio, CR, in the range from 2.0 and 5.0.

Abstract: Base cup (30) for receiving a container body bottom (15) and for reducing heat gain to fluid contents in the container body (12). A passive base cup is made of foam and has a reflective layer (44) on a majority of the outer surface thereof, or made of plastic, with an outer reflective layer, and optionally a foam layer (46). An active base cup (60) server to actively cool the fluid in the container, by including a compartment (66) therein with a fluid (68) that can be frozen. Again, a reflective layer and an optional foam layer extend over a majority of the outer surface of the cup. The reflective layer (44) materials have a density different than the cup materials to facilitate recycling.

Abstract: A crystallization process comprising passing a mass of amorphous crystallizäble polymer having a first thickness (ft) through the nip gap of counter-rotating rolls having a nip gap (ng)at an ft:ng ratio of at least 1.2 to crystallize the polymer to a degree of crystallinity of at least 15% and thereby produce a semi-crystalline polymer, and particulating the semi-crystalline polymer. Strain crystallizing a sheet or fiber by using a drafting step to elongate the sheet or fiber is no longer needed. A high degree of crystallinity is imparted almost instantaneously, even in slow to crystallize copolyesters. The process allows one to extrude a thinner crystallizable sheet, substantially retains the dimensiona) width of the sheet as it is passed through the compression rolls, and produces substantially optically clear sheet and pellets. Suitable polymers include polyethylene terephthalate or naphthalate homopolymers or copolymers.

Abstract: An apparatus and a method for molding of polyester articles having low acetaldehyde content directly from a melt without intermediate solidification of the molten polyester. A melt to mold process is used wherein an acetaldehyde stripping agent is mixed into a polyester melt before devolatilization in a flash tank. The devolatilized polyester is pumped out of the flash tank and injected into a mold, thus forming a shaped article. The apparatus may include one or more flash tanks in one devolatilization line, or multiple devolatilization lines may be used stemming from one main polymerization reactor. The final shaped article should contain less than 10 ppm of acetaldehyde.
