    摘要： Specific methods of inducing high nucleation rates in thermoplastics, such as polyolefins, and particularly, though not necessarily, polypropylenes, through the introduction of two different compounds that are substantially soluble within the target molten thermoplastic resin (such as, as one non-limiting example, an added compound including at least one acid group and an added organic salt) are provided. Such introduced components react to form a nucleating agent in situ within such a target molten thermoplastic resin which is then allowed to cool. Preferably, one compound is an acid, preferably bicyclic (i.e., two cyclic systems sharing at least three carbon atoms) or monocycloaliphatic (i.e., a single, saturated ring system) in nature, such as, without limitation, bicyclo[2.2.1]heptane dicarboxylic acid or hexahydrophthalic acid, and the other compound is an organic salt, such as a carboxylate, sulfonate, phosphate, oxalate, and the like, and more preferably selected from the group consisting of metal C8–C22 esters. Such a production method thus provides a manner of generating in Situ the desired nucleating agent through reaction of such soluble compounds. Kits (e.g., masterbatch methods, for example) comprising such components for easy introduction within target molten polyolefin resins are also contemplated within this invention.

    摘要： This invention relates to improvements in preventing heat- and moisture-shrink problems in specific polypropylene fibers. Such fibers require the presence of certain compounds that quickly and effectively provide rigidity to the target polypropylene fiber after heat-setting. Generally, these compounds include any structure that nucleates polymer crystals within the target polypropylene after exposure to sufficient heat to melt the initial pelletized polymer and upon allowing such a melt to cool. The compounds must nucleate polymer crystals at a higher temperature than the target polypropylene without the nucleating agent during cooling. In such a manner, the “rigidifying” nucleator compounds provide nucleation sites for polypropylene crystal growth. After drawing the nucleated composition into fiber form, the fiber is then exposed to sufficient heat to grow the crystalline network, thus holding the fiber in a desired position. The preferred “rigidifying” compounds include dibenzylidene sorbitol based compounds, as well as less preferred compounds, such as sodium benzoate, certain sodium and lithium phosphate salts (such as sodium 2,2′-methylene-bis-(4,6-di-tert-butylphenyl)phosphate, otherwise known as NA-11). Specific methods of manufacture of such fibers, as well as fabric articles made therefrom, are also encompassed within this invention.

    摘要： This invention relates to a fluid dispersion of at least one dibenzylidene sorbitol acetal derivative. The sorbitol acetal derivative is useful as a clarifying agent for polyolefins and the inventive fluid dispersion permits improvements in the handling and processing of and mixing within the polyolefin composition. The inventive dispersion must be shelf stable, retain its nucleating effects, be compatible with polypropylene (and other polyolefins), and possess both short-term and long-term viscosities which permit acceptable transport through a standard polyolefin-manufacturing peristaltic pump. The preferred inventive dispersion thus comprises 3,4-DMDBS and at least one ethoxylated nonionic surfactant having an HLB of greater than about 8.5. Preferred surfactants include those selected from the group consisting essentially of ethoxylated sorbitan (C.sub.8 -C.sub.22) monoesters and ethoxylated nonyl-phenol ethers. The inventive dispersion may be introduced within any polyolefin composition, preferably polypropylene, which may then be molded into any shape or form. A method of producing a polyolefin plastic utilizing the inventive dispersion is also provided.
