  • Polyolefin additive composition comprising 3,4-dimethyldibenzylidene sorbitol and p-methyldibenzylidene sorbitol
    Patent number: 6989154
    Abstract: A specific combination of two different polyolefin clarifying and nucleating agents, namely 3,4-dimethyldibenzylidene sorbitol and p-methyldibenzylidene sorbitol is provided. Such a combination surprisingly provides improved clarification and crystallization temperatures to polypropylene articles and formulations, better than bis-p-methyldibenzylidene sorbitol alone and equivalent or better than 3,4-dimethyldibenzylidene sorbitol. Such a combination of compounds thus permits the utilization of a new additive for the purpose of modifying polyolefin properties, such as polypropylene clarification and nucleation. The inventive combination may be introduced within any polyolefin composition, again preferably polypropylene, which may then be molded into any shape or form. A method of producing a polyolefin plastic utilizing the inventive combination of compounds is also provided.
    Type: Grant
