摘要： It is possible to improve significantly the optical performance of diacetal or DBS-based nucleating or clarifying agents using a co-additive. Haze is a measure of the lack of clarity in a thermoplastic or plastic material. A low level of haze is usually quite desirable, and nucleating/clarifying agents are designed to reduce the degree of haze in a plastic or thermoplastic material. A co-additive may be used in connection with a nucleating/clarifying agents in a polymer or copolymer to achieve even greater results in terms of improved clarity (reduced haze), or in terms of a higher crystallization temperature (Tc) of the polymer. A method for reducing haze in polymer articles using a co-additive composition in addition to nucleating and clarifying agents is disclosed.

摘要： 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. Methods of production and liquid UV absorber/individual bluing agent formulations are also encompassed within this invention.

摘要： Combinations of at least two individual colorant 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 combination 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 a combination of compounds 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 inventive combination bluing agent accords effective neutralization of UV absorber yellowing as well.
