  • Patent number: 7262236
    Abstract: An acetal-based composition useful as a nucleating, gelling, thickening or clarifying agent is disclosed. The composition may be synthesized or provided in many different forms, including multicarbon diacetals formed from carbohydrates. Once synthesized, the compound may be employed as an additive in a plastic composition, such as (for example) a polypropylene copolymer. One structure of such an acetal-based composition is provided by the formula: wherein: n is 0, 1 or 2; Ar1 and Ar2 are independently selected from substituted or unsubstituted aryl-containing groups; and R is selected from the group consisting of: alkenyls, alkyls, alkoxy, hydroxyl alkyls, and alkyl-halides.

  • Patent number: 7157510
    Abstract: An acetal-based composition useful as a nucleating, gelling, thickening or clarifying agent is disclosed. The composition may be synthesized or provided in many different forms, including multicarbon diacetals formed from carbohydrates. Once synthesized, the compound may be employed as an additive in a plastic composition, such as (for example) a polypropylene copolymer. Co-additives may also be employed. Several aryl structures may reside upon the hydrocarbon chain backbone. One structure of such an acetal-based composition which happens to have two aryl-containing groups is shown: wherein: n is 0, 1 or 2; Ar1 and Ar2 are independently selected from substituted or unsubstituted aryl-containing groups; and R is selected from the group consisting of: alkenyls, alkyls, alkoxy, hydroxyl alkyls, and alkyl-halides.

  • Patent number: 7144939
    Abstract: The use of organic based nucleating agents to induce certain specific polymer orientations into the molded polypropylene articles such that the resultant part has improved stiffness-impact properties without sacrificing other attributes of the polypropylene is provided. Such results have been obtained through the utilization of low amount of organic nucleating compounds, including, without limitation, specific metal salts of hexahydrophthalic acid (hereinafter HHPA). Furthermore, such nucleating compounds have been found to impart, again in such low added amounts, heretofore unforeseen levels of b-axis crystalline orientation which translates into improved physical properties as well.

  • Patent number: 7129323
    Abstract: 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.

  • Patent number: 6972306
    Abstract: Certain multi-substituted dibenzylidene sorbitol acetals having electron withdrawing groups as constituents and electron donating groups on the other such that the compounds are asymmetric in structure and are dipolar in nature are provided. Polymer compositions comprising such compounds, are also contemplated which may be utilized within, as merely examples, food or cosmetic containers and packaging. These inventive asymmetric dipolar dibenzylidene sorbitol acetals are also useful as gelling agents for water and organic solvents, particularly those used in the preparation of antiperspirant gel sticks.

  • Patent number: 6878443
    Abstract: Unique thermoplastic (polypropylene, specifically) monofilament and/or tape fibers and yarns that exhibit heretofore unattained physical properties are provided. Such fibers are basically manufactured through the extrusion of thermoplastic resins that include a certain class of nucleating agent therein, and are able to be drawn at high ratios with such nucleating agents present, that the tenacity and modulus strength are much higher than other previously produced thermoplastic fibers (particularly those produced under commercial conditions), particularly those that also simultaneously exhibit extremely low shrinkage rates. Thus, such fibers require the presence of certain compounds that quickly and effectively provide rigidity to the target thermoplastic (for example, polypropylene), particularly after heat-setting.

  • Patent number: 6599968
    Abstract: Compounds and compositions comprising specific metal salts of bicyclo[2.2.1]heptane dicarboxylate salts in order to provide highly desirable properties within polyolefin articles are provided. The inventive salts and derivatives thereof are useful as nucleating and/or clarifying agents for such polyolefin, provide excellent crystallization temperatures, stiffness, and calcium stearate compatibility within target polyolefin. Also, such compounds exhibit very low hygroscopicity and therefore excellent shelf stability as powdered or granular formulations. Polyolefin additive compositions and methods of producing polyolefin with such compounds are also contemplated within this invention.
