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： The present invention relates to methods of producing syndiotactic polypropylene articles through high performance nucleation via the presence of certain novel nucleating agents within molten syndiotactic resins, and subsequently permitting the resultant molten mixture to cool into a selected shape or configuration. Such novel nucleating agents are new classes of hyper-nucleators that promote crystallization within such target syndiotactic resins at levels well above any previously disclosed nucleators. This invention thus also encompasses the articles and compositions of such nucleated syndiotactic polypropylene as well.

摘要： This invention relates to plastic additives which are useful as nucleating agents and which are especially useful for improving the optical properties of polymeric materials. More particularly, this invention relates to certain bis-halogen-alkyl-benzylidene alditol acetals and polymer compositions thereof which are useful as materials for food or cosmetic containers and packaging. These bis-halogen-alkylbenzylidene alditol acetals are also useful as gelling agents for organic solvents, particularly those used in the preparation of antiperspirant gel sticks.

摘要： Plastic additives which are useful as nucleating agents and which are especially useful for improving the optical properties of polymeric materials are provided. More particularly, this invention relates to certain alkyl (or alkoxy) substituted halo-benzylidene sorbitol acetals and polymer compositions thereof which may be utilized within, as merely examples, food or cosmetic containers and packaging. These inventive halogenated (that is, chlorinated, brominated, or iodinated) and alkylated benzylidene sorbitol acetals are also useful as gelling agents for water and organic solvents, particularly those used in the preparation of antiperspirant gel sticks.
