| In forming containers by distending preforms of nitrile thermoplastic material at molding temperature, the improvement comprising exposing such preforms to low dosage radiation to reduce residual nitrile monomer in the thermoplastic material and then distending the irradiated preforms to cause HCN generated during irradiation to flash off in forming the container. The containers formed have unusually low concentrations of residual nitrile monomer as well as extractable HCN making them especially suitable for packaging foods, beverages, pharmaceuticals and the like. The irradiated preforms from which such containers are made have similarly low residual nitrile monomer levels. | ||||||

| In forming containers from injection molded preforms of thermoplastic material such as nitrile-based polymers by a process which includes heating the preforms to orientation temperature followed by distension to container form in a mold, the improvement providing reduced thickness variability in lower portions of the containers which involves controlling preform shrinkage during such heating to between about 4 to 15% of the initial length for nitrile materials by maintaining the ratio of average thickness to inside preform surface area within defined limits and then axially and radially stretching such preforms during distension to predetermined levels. Nitrile preforms convertible to such improved quality containers have values of between about 0.005 to 0.011 inch.sup.-1 for the aforementioned ratio. | ||||||

| TUBULAR PREFORMS FORMED OF A SYNTHETIC RESIN, THE MAJOR CONSTITUENT OF WHICH IS POLYMERIZED NITRILE MONOMER SELECTED FROM THE GROUP CONSISTING OF ACRYLONITRILE, METHACRYLONITRILE AND MIXTURES THEREOF, ARE RAPIDLY HEATED TO A TEMPERATURE AT WHICH MOLECULAR ORIENTATION OCCURS ON STRETCHING BY EXPOSING THE BOODY PORTIONS OF SUCH PERFORMS TO MICROWAVE ENERGY FOR A PRIOD OF FROM 1/2 TO 30 SECONDS TO HEAT SUCH BODY PORTIONS TO A TEMPERATURE OF BETWEEN 250 TO 320* F. WITHOUT DEFORMING A PRIOR MOLDED FINISHED NECK SECTION THEREOF AND WITHOUT SUBSTANTIALLY DEGRADING THE RESIN.

Preforms, for conversion into containers for environmentally sensitive materials, made of thermoplastic material comprising at least 20 weight percent of a polymerized nitrile group-containing monomer and an effective amount of an HCN scavenger are characterized by containing no more than about 1.5 ppm of unpolymerized nitrile group-containing monomer based on the total weight of the thermoplastic material. The performs can be obtained by subjecting a conventional preform to low dosage electron beam irradiation. |
