    Abstract: The present invention provides methods for assessing the performance of one or more test olefin polymerization catalysts which comprise one or more metals. The methods are based on the use of coordinating-reactive quencher molecules that are added to polymerization reactions to tag oligomers and optionally to tag polymers that were bound to active catalyst at the time of quenching. The tag allows the identification and analysis of the molecular weight, length, and structure of oligomers and polymers generated by the activated catalyst as a function of reaction time as well as other polymerization process parameters. Evaluation of the presence or absence of tagged oligomers and polymers, the relative molecular weights, lengths and/or structure of the tagged oligomers and polymers and/or the determination of the relative or absolute amounts of tagged oligomer and polymers generated on quenching provide information which can be used to assess the performance of one or more activated polymerization catalyst.

    Abstract: An automatic optical lens sun shield comprises an elastic clip cartridge, a rotary connector and a tinted transparent optical lens screen. The elastic clip cartridge is constructed with spring clamp frames which can be pulled outward and clipped on an original padded visor as well as detached from the original padded visor without using any hand tool. The rotary connector is constructed with a positioning pivot shaft which drives the positioning pad to rotate. Thereby, the radiating teeth at the bottom of the positioning pad is engaged to the radiating positioning teeth of the rotating connector. Therefore, the rotary connector can rotate under the clip cartridge and is securely positioned thereon. The lower part of the rotary connector is formed with at least one pivot groove. The tinted transparent optical lens screen is engaged to the pivot groove via a rotary shaft.
