US Classification:

524108, 524583, 525938, 549364, 25218213

Abstract:

Clarified polyolefins such as polypropylene are used widely to make polymer articles, containers, and the like. Such articles may be manufactured by the injection of molten polymer into a mold or forming device in manufacturing processes at high rates. A clarified composition is provided to achieve optimized clarity and organoleptic performance at lower processing temperatures and/or within a polypropylene resin having a higher melt flow rate.

US Classification:

Abstract:

Nucleating agent compounds are used in polymers, such as polypropylene, to improve both the properties and processing characteristics of the polymer. Some nucleating agents may be used also as clarifiers to reduce the visual haze in finished polymeric articles, thereby increasing clarity of finished polymeric articles. Compounds of a carboxylate salt which employ a combination of an amide group and a metal cation salt perform well as nucleating agents, and provide substantial clarity benefits in a polymer. Other compounds of the invention may employ metal carboxylate salts in combination with an ester group. In other embodiments of the invention a dimer of such compounds may be employed.

US Classification:

524493, 106819

Abstract:

Diacetals of sorbitols and xylitols are employed in polyolefins as nucleating agents. Diacetals of sorbitols and xylitol nucleating agents may be provided in granular or powder form from hoppers or mixing equipment into polyolefins during the formation of polymeric compositions and polymeric articles. Flow of diacetals of sorbitols and xylitols is improved by the use of certain silicas, in certain defined weight percentages. Submicron size range silica compounds may provide excellent flow enhancement properties when blended and used with diacetals of sorbitols and xylitols powder compounds. A hydrophobic silica mixed with diacetals of sorbitols and xylitols compounds also may provide enhanced flow properties for such mixture, as compared to mixtures using hydrophilic silica. Loading ranges of silica may be important in improving the flow of diacetals of sorbitols and xylitols compounds.

Abstract:

Chemical additives disclosed for reducing “plate-out” which have applications in polymers, such as polyolefins. It is possible to provide for a composition and a process for producing parts, sheet and film from polyolefin extrusion applications wherein the polyolefins are processed with a minimal quantity of “plate-out. ” A polyolefin composition may contain a sorbitol-based clarifying system of a derivative of Dibenzylidene, along with one or more co-additives to achieve a reduction in undesirable plate-out.

US Classification:

Abstract:

It is possible to improve significantly the optical performance of diacetal or DBS-based nucleating or clarifying agents using a co-additive. Haze is a measure of the lack of clarity in a thermoplastic or plastic material. A low level of haze is usually quite desirable, and nucleating/clarifying agents are designed to reduce the degree of haze in a plastic or thermoplastic material. A co-additive may be used in connection with a nucleating/clarifying agents in a polymer or copolymer to achieve even greater results in terms of improved clarity (reduced haze), or in terms of a higher crystallization temperature (Tc) of the polymer. A method for reducing haze in polymer articles using a co-additive composition in addition to nucleating and clarifying agents is disclosed.
