    Abstract: Disclosed are novel anthraquinone compounds containing tetra-p-phenylenediamine substituents, particularly useful in molding type polyester compositions and possessing strong infrared absorptivity. This property renders these compounds attractive as additives for increasing the infrared energy absorptivity of polyesters either from high intensity quartz lamps or from certain laser systems. These compounds are particularly useful in bottle polyester material for increasing the blow-mold parison reheat rate, and in the printing of plastic articles with lasers.

    Abstract: Disclosed is a process for the manufacture of high molecular weight polyesters, particularly poly(ethylene terephthalate) (PET) and modified PET, having inherent viscosities (I.V.) for example, above about 0.6, and up to about 1.3 or higher. Such polymers are useful, for example, as structural moldings, self-supporting sheets and films, and blow-molded bottles. The process involves one or more recrystallizations of the polymer incident to solid-state polycondensation, which recrystallizations, it has been discovered, restores the high polycondensation activity of the polymer experienced in the early stages thereof and allows greatly increased overall build-up rate and higher final I.V. for the total polycondensation period. The process is particularly applicable to crystallizable polyesters in general which lend to solid-state build-up.

    Abstract: A container 22 includes a shell 24 made from a polymer, for example PET, and incorporating a catalyst, for example a palladium catalyst. A closure 40 incorporates a plug which includes a source of hydrogen, for example a hydride. In use, with container 22 including a beverage and closure 40 in position, the headspace in the container will be saturated with water vapor. This vapor contacts the hydride associated with plug 42 and as a result the hydride produces molecular hydrogen which migrates into the polymer matrix of shell 24 and combines with oxygen which may have entered the container through its permeable walls. A reaction between the hydrogen and oxygen takes place, catalysed by the catalyst, and water is produced. Thus, oxygen which may ingress the container is scavenged and the contents of the container are protected from oxidation.
