Abstract: This invention pertains to highly filled polymer compositions comprising a low molecular weight ethylene and/or alpha olefin homopolymers and copolymers, or blends therefrom, filled with high concentrations of fillers or additives. Examples of such fillers or additives include fire retardants, talc, ceramic manufacturing agents, color concentrates, crosslinking agents, and blowing agents. Because of the low crystallinity (and therefore high percentage of amorphous phase) and low viscosities of the base polymers, highly processable compositions can be formed containing even if containing relatively high loadings of fillers or additives. Such highly filled compositions are thus ideally suited as concentrates or masterbatch formulations for a variety of different compounding applications.

Abstract: The present invention incorporates new processes for blending derivatized carbon nanotubes into polymer matrices to create new polymer/composite materials. When modified with suitable chemical groups using diazonium chemistry, the nanotubes can be made chemically compatible with a polymer matrix, allowing transfer of the properties of the nanotubes (such as mechanical strength) to the properties of the composite material as a whole. To achieve this, the derivatized (modified) carbon nanotubes are physically blended with the polymeric material, and/or, if desired, allowed to react at ambient or elevated temperature. These methods can be utilized to append functionalities to the nanotubes that will further covalently bond to the host polymer matrix, or directly between two tubes themselves.

Such nucleating additives have been found to impart high peak crystallization temperatures to thermoplastics (such as polypropylene, as one example); however, when combined in masterbatch form in the past such a nucleation property was sacrificed due to unforeseen problems associated with polymer-containing concentrates (i.e., pellets, for example) of such additives. Thus, improvements in masterbatching of these bicyclic dicarboxylate salt thermoplastic nucleators has been accomplished to the level necessary to allow for concentrate use with concomitant effective nucleation effects at the same level (if not in excess thereof) of the utilization of such a nucleator added in powder form.

Abstract: Concentrates (also known as masterbatches) of certain bicyclic dicarboxylate salt thermoplastic nucleating additives in order to facilitate use thereof in typical thermoplastic manufacturing procedures are provided. Such nucleating additives have been found to impart high peak crystallization temperatures to thermoplastics (such as polypropylene, as one example); however, when combined in masterbatch form in the past such a nucleation property was sacrificed to a certain extent due to unforeseen problems associated with polymer-containing concentrates (i.e., pellets, for example) of such additives. Thus, improvements in masterbatching of these bicyclic dicarboxylate salt thermoplastic nucleators have been accomplished to the level necessary to allow for concentrate use with concomitant effective nucleation effects at the same level (if not in excess thereof) of the utilization of such a nucleator mixed prior to melt-compounding with a target or resin or added directly into a molten resin (i.e.

Such small particle size dicarboxylate salts provide desirable properties within thermoplastic articles, particularly as nucleating agents, but apparently suffer from certain clarity issues and agglomeration problems (due to the flat and thin plate structures of such compounds and the propensity they exhibit to cohere to each other during storage), making utilization thereof less desirable for certain applications. Thus, an improvement has been provided to permit full benefit of the excellent crystallization temperatures, stiffness, and calcium stearate compatibility such dicarboxylate salts accord within target low haze thermoplastics.
