Patent number: 10800902Abstract: A method for producing a thermoplastic polymer composition comprises the steps of separately providing a thermoplastic polymer and an additive composition and then mixing the thermoplastic polymer and additive composition. The additive composition comprises a clarifying agent and a coloring agent. Another method for producing a thermoplastic polymer composition comprises the steps of separately providing a thermoplastic polymer, a clarifying agent, and a coloring agent and then mixing the thermoplastic polymer, the clarifying agent, and the coloring agent. The coloring agent is present in the composition in an amount to yield a composition exhibiting CIE L*, a*, and b* values falling within a defined color space. An additive composition contains a clarifying agent and a coloring agent.Type: GrantFiled: April 12, 2017Date of Patent: October 13, 2020Assignee: Milliken & CompanyInventors: Todd D.

Patent number: 8653165Abstract: Thermoplastic articles may be manufactured having a high degree of visual appeal to consumers. Clarifying agents may be employed as additives in such thermoplastic articles to produce high clarity articles. A coloring agent may be mixed with clarifying agents to form a first blend, and then such a first blend may be applied in very low loadings to form a clarified polymeric article. It is possible to achieve an observable visual benefit while using very low loadings of coloring agent in a polyolefin, such as polypropylene. Carbon black is a pigment that may provide such observable benefits in polypropylene.Type: GrantFiled: June 26, 2012Date of Patent: February 18, 2014Assignee: Milliken & CompanyInventors: Todd D. Danielson, Jennifer Rockwood, Nathan A. Mehl

Patent number: 7662978Abstract: The present invention relates to dibenzylidene sorbitol (“DBS”)-based compounds. The compounds of this invention are particularly advantageous in that they are characterized by one or more of improved transparency (reduced haze), reduced yellowing and/or improved organoleptics (taste). According to one embodiment, the present invention provides a disubstituted DBS-based compound having an allyl group or a propyl group substituted on the first carbon of the sorbitol chain. The present invention also relates to compositions comprising such DBS-based compounds and methods for using them.Type: GrantFiled: January 31, 2007Date of Patent: February 16, 2010Assignee: Milliken & CompanyInventors: Chunping Xie, Lee R. Rieth, Todd D. Danielson

Patent number: 7014797Abstract: Novel ultraviolet absorbing compounds that are liquid in nature, are extremely low in color and are highly effective in providing protection in wavelength ranges for which previous attempts at low-color ultraviolet absorbers have failed are provided herein. Such compounds provide such excellent, inexpensive, and beneficial protection from ultraviolet exposure within various media, including, but not limited to, clear thermoplastics. The particular compounds are generally polymeric in nature including various chain lengths of polyoxyalkylenes thereon and are liquid in nature to facilitate handling and introduction within the target media. In addition, such ultraviolet absorbers also exhibit extremely low migratory properties thereby providing long-term protective benefits to the target media as well.Type: GrantFiled: December 31, 2002Date of Patent: March 21, 2006Assignee: Milliken & CompanyInventors: Todd D. Danielson, Xiaodong E. Zhao, Mary E. Mason, Daniel M. Connor, Eric B. Stephens, Jason D. Sprinkle, Jusong Xia

Patent number: 6891058Abstract: Novel ultraviolet absorbing compounds that are liquid in nature, are extremely low in color (and thus permit use without the concomitant necessity of adding large amounts of other coloring agents to combat such discoloring), and are highly effective in providing protection in wavelength ranges for which previous attempts at low-color ultraviolet absorbers have failed are provided herein. Such compounds provide such excellent, inexpensive, and beneficial protection from ultraviolet exposure within various media, including, but not limited to, clear thermoplastics. The particular compounds are generally polymeric in nature including various chain lengths of polyoxyalkylenes thereon and are liquid in nature to facilitate handling and introduction within the target media.

Patent number: 6875811Abstract: Individual compounds that provide effective toning (or bluing) to combat yellowing within polyester articles (such as bottles, containers, and the like) are provided. Such a novel toner permits effective neutralization of yellowness while also providing highly desirable low haze and increased brightness due to a sharp absorption peak within the needed range of wavelengths (e.g., from about 565 to 590 nm) and a narrow half-height band width. Furthermore, such an individual compound is preferably liquid in nature and may thus be incorporated within an added ultraviolet absorber solution or shelf-stable dispersion to facilitate addition within target polyesters at various stages of production. The particular UV absorbers desired as additives within target polyesters also tend to exhibit certain yellowing effects that require attention as well. The inventive single bluing agent compound thus also accords effective neutralization of such UV absorber yellowing as well.Type: GrantFiled: May 7, 2002Date of Patent: April 5, 2005Assignee: Milliken & CompanyInventors: Todd D. Danielson, Jason Sprinkle, Daniel Connor, Donnie Hyder

Patent number: 6733708Abstract: An improved procedure and apparatus for introducing liquids within a thermoplastic or thermoset production system are provided. Such an inventive apparatus comprises a storage tank for the desired liquid, a device which connects to a flow channel (such as a manifold or pipe) through which the target thermoplastic or thermoset composition is flowing, and a transfer line connecting the storage tank with the connecting device. The connecting device itself easily attaches and detaches to the flow channel through a spring-loaded or sliding-lock mechanism. Such a novel apparatus permits an ease in changeover from one liquid to another without the need for time-consuming cleaning and without complicated shut-off, removal, and replacement steps.Type: GrantFiled: April 17, 2003Date of Patent: May 11, 2004Assignee: Milliken & CompanyInventors: Jimmy D.
