摘要： A process is provided for the production of a very low melt viscosity (high melt flow index) polymer resin, suitable for use in spunbond or meltblown processing. According to the process of the current invention, a high melt viscosity (low melt flow index) resin is subjected to post-reactor molecular weight alteration by extrusion with a chemical prodegradant. The process produces a very low melt viscosity resin that can be used in spunbond or meltblown processing without further treatment to reduce the average molecular weight of the resin. Further, the very low melt viscosity resins produced according to the process of the current invention contain very little or no residual prodegradant.

摘要： The present invention provides additive packages for polyolefins The additive packages of the present invention comprise at least one non-phenolic antioxidant and a hindered amine light stabilizer. The additive packages may contain other additives as needed, and may optionally include an acid scavenger. Articles made from the resultant polymers, such as radiator surge tanks, exhibit enhanced stain and discoloration resistance upon exposure to high temperatures and harsh chemicals such as those experienced in “under the hood” spaces of modern automobiles.

摘要： A method of manufacturing an improved clarity, low haze, low melt flow rate homopolymer polypropylene and thermoformed parts therefrom using an additive package such that the additive package alone provides the improved qualities, and process adjustments at the thermoforming stage are not required. The additive package does not contain a phosphite antioxidant, and the homopolymer polypropylene is either virgin material or virgin material mixed with at least 25 percent reground homopolymer polypropylene of the improved formulation described herein and combined with the improved clarity additive package.

摘要： Method of manufacturing inorganic polymer hybrids with improved mechanical properties and even dispersion of the inorganic material in the hybrids. Nanoscale exfoliation of inorganic materials having layered structures is induced, and said inorganic materials are combined with an emulsion comprising one or more molten polymers. The method provides nanoscale dispersion of inorganic material throughout the emulsion of one or more polymers without the use of compatibilizers.
