Abstract: An additive composition comprises phosphate ester anions conforming to a specified structure, aromatic carboxylate anions, optionally cycloaliphatic dicarboxylate anions, aluminum (III) cations, sodium cations, optionally calcium cations, optionally lithium cations, and optionally zinc (II) cations. The anions are present in the additive composition in specified molar percentages. The cations are also present in the additive composition in specified molar percentages.

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.

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.
