Abstract: Novel compounds derived from traditional semi- drying and non-drying oils featuring internally plasticizing and crosslinkable properties are disclosed and claimed. Preferred embodiments include acrylate or methacrylate esters of hydroxy long-chain olefinic compounds derived from castor oil or lesquerella oil. A process for the preparation of the novel compounds is also disclosed, which involves esterification reaction of ethylenically unsaturated carboxylic acids or its derivatives with substituted hydroxy long-chain olefinic compounds. These compounds are suitable for forming latices, which form films at low minimum film forming temperatures (MFT) ranging from −5 to 10° C. and cure to above ambient glass transition (Tg) polymers without the use of traditional organic cosolvents which contribute to environmental pollution via volatile organic compounds (VOCs) emissions. These latices are therefore useful in waterborne coatings, contact and pressure sensitive adhesives, and inks.

Abstract: Bicyclic nucleator compounds that provide highly versatile nucleation benefits for different polyolefins are provided. Such nucleator compounds provide very high peak crystallization temperatures and significantly reduced crystallization cycle time for certain thermoplastic formulations with or without the presence of other calcium stearate and/or peroxide components within the same type of formulation. Furthermore, such inventive nucleator compounds exhibits very little if any fugitivity from such thermoplastic formulations thereby providing excellent processing characteristics as well as excellent nucleation capabilities for a variety of different thermoplastic resins, independent of the presence of different, potentially necessary, additives (such as calcium stearate). Thermoplastic compositions as well as thermoplastic additive packages comprising such inventive nucleator compounds are also contemplated within this invention.

Abstract: Certain thermoplastic additives (combinations of clarifying and nucleating compounds) that induce simultaneously low clarity and high nucleation efficacy are provided. Such additives include combinations of certain bicyclic salts (which by themselves induce very high nucleation efficacy) and thermoplastic clarifying agents, including certain dibenzylidene sorbitol acetals and derivatives (hereinafter collectively referred to as “DBSs”)(which alone provide very low haze measurements and thus highly desirable clarity characteristics). In comparison, other types of standard thermoplastic nucleators, such as sodium benzoate and sodium 2,2′-methylene-bis-(4,6-di-tert-butylphenyl) phosphate provide relatively high peak crystallization temperatures, but do not combine synergistically with clarifiers, such as DBSs, to provide the same results as for the inventive combination of bicyclic salts and DBSs.

Abstract: The present invention is directed to a an accelerator-gel additive used to deliver an accelerator such as sulfur, into a system for the production of polymer modified asphalt, vulcanized rubber or similar system. Unlike conventional methods of delivering accelerator into the system, the accelerator-gel additive suspends the accelerator in a gel system thereby preventing the sedimentation of the accelerator during processing. As a result, the polymer and asphalt are processed at lower temperature reducing the production of toxic and flammable gases such as hydrogen sulfide.
