The invention relates to stabilizer compositions for polymers such as polyolefin polymers, which decrease a phosphorus based stabilizer content necessary to stabilize the polymer. The premixed stabilizer compositions include an antacid, an organic acid-metal salt, and a primary antioxidant such as a sterically-hindered phenolic compound, a sterically-hindered amine compound, a hydroxylamine compound, and combinations thereof. The premixed stabilizer may further include a portion of the phosphorus based stabilizer content necessary to stabilize the polymer. The invention also relates to a method for the preparation of the stabilized polymer compositions provided by the use thereof.

Stabilized polymer compositions and methods of making same

A polyalkyl benzimide polymeric dispersant produced from the reaction product of polyisobutylene amine with 1,2,4-benzenetricarboxylic anhydride, and method of preparing same and colorant dispersions containing dispersant.

Polymeric dispersants and dispersions containing same

Certain poly(oxyalkylene) colorants are disclosed along with method of preparation thereof. A method of using these colorants as fluorescent security taggants is also disclosed.

Poly(oxyalkylene)ated colorants and their use as fluorescent security taggants

Polymeric colored dispersant having the structure A-(B&#x2014;X), where A is an organic chromophore; B is a covalently bonded linking moiety; X is a branched or linear C-Cpolymeric covalently linked hydrocarbon, and n is an integer from 1 to 4, and low viscosity colorant dispersions containing same having a relative interfacial tension drop of less than about 1.5.

Polymeric colored dispersants and colorant dispersions containing same

Dispersants for pigments as well as dispersions of pigments containing them, and compositions such as inks and coatings containing them are described. The dispersants are the reaction product of a dialkylsuccinyl succinate and an amine.

Polymeric dispersants based on addition of amines to dialkylsuccinyl succinate or its derivatives

Phthalocyanine blue pigments and pigment dispersions for water-borne inks and coatings are described. The pigments are produced by dry milling phthalocyanine blue and a polymeric dispersant, optionally with inorganic fillers and other additives, to obtain a material with improved coloristic, rheological, and stability properties. The resulting activated crude is then processed directly into water-based pigment dispersion with additives and/or surfactants to facilitate conversion to pigmentary form while maintaining the desirable green and clean shade.

Copper phthalocyanine blue pigment composition and water borne dispersion thereof

Pigment dispersions that when used in printing ink having a relative interfacial tension drop of less than 1.5, and offering an ink viscosity of less than 150 Pa.s, and containing at least 45 wt. % pigment.

Low viscosity, highly pigmented oil based dispersions exhibiting a low relative interfacial tension drop
