    摘要: Crystalline propylene polymer compositions having improved impact strength and improved clarity are disclosed. The composition is prepared by melt blending a propylene polymer, e.g., polypropylene, and from about 1 to 35 wt % of an elastomeric interpolymer of a C.sub.4 to C.sub.8 isomonoolefin, e.g., isobutylene, and a para alkystyrene comonomer, e.g., para-methylstyrene. The interpolymer preferably contains a benzylic functional group such as halogen (bromine). The composition may also contain from about 0.5 to 15 wt % of the amide reaction product of an organic acid-grafted propylene polymer, e.g., maleic anhydride grafted polypropylene, and a polyfunctional primary amine.

    摘要: Methods of tailoring polyethylenes are contemplated utilizing 0.5 to 70 volume percent oxygen containing gases. The tailoring occurs in a melt-conveying zone of a mixer/extruder, and not in the feed or melting zones of a mixer/extruder. The effect of tailoring is to decrease the haze and/or increase the gloss of blown films made from the tailored polyethylenes compared to similar polyethylenes that are extruded/mixed in the substantial absence of oxygen or oxygen containing gases.

    摘要: An apparatus includes a lamp-control circuit. The lamp-control circuit is configured to be electrically connectable to an electrical source having an output voltage that forms a periodic wave formation. The lamp-control circuit is also configured to be electrically connectable to a lamp array. This is done in such a way that electrical current, in use, flows from the electrical source to, and through, the lamp array. The lamp array includes lamp segments. The lamp-control circuit is also configured to urge each lamp segment of the lamp array to consume relatively constant power for a portion of a cycle of the output voltage of the electrical source in such a way that said each lamp segment of the lamp array, in use, emits a relatively constant light output for the portion the cycle of the output voltage of the electrical source.
