Stabilizer compositions having a stabilizing amount of at least one co-active agent; an ultraviolet light absorber chosen from orthohydroxyphenyl triazine compounds and/or benzoxazinone compounds; and a hindered amine light stabilizer, are provided herein, along with masterbatch concentrates containing same, and processes for using same for stabilizing polymeric organic materials to protect against light and thermal degradation due to exposure to UV irradiation.

Stabilizer compositions and methods for using same for protecting polymeric organic materials from UV light and thermal degradation

Stabilizer compositions having a stabilizing amount of at least one co-active agent; an ultraviolet light absorber chosen from an ortho-hydroxy benzophenone, and/or an ortho-hydroxyphenyl benzotriazole; and a hindered amine light stabilizer, are provided herein, along with masterbatch concentrates containing same, and processes for using same for stabilizing polymeric organic materials to protect against light and thermal degradation due to exposure to UV irradiation.

Stabilized compositions having an organic material to be stabilized and a resin masterbatch system provided as closed end pellets are provided herein, along with processes for producing stabilized articles.

Stabilized compositions and process for producing same

Stabilizer compositions having a stabilizing amount of at least one co-active agent; and a stabilizing amount of any one or more ultraviolet light absorber chosen from an ortho-hydroxyphenyl triazine, an ortho-hydroxy benzophenone, or an ortho-hydroxyphenyl benzotriazole, optionally in combination with a stabilizing amount of a hindered amine light stabilizer, are provided herein, along with masterbatch concentrates containing same, and processes for using same for stabilizing organic materials to protect against light and thermal degradation due to exposure to UV irradiation.

Stabilizer compositions and methods for using same for protecting organic materials from UV light and thermal degradation

Resin masterbatch compositions are provided as closed end pellets having a core including at least one additive and an outer layer comprising a polymer encapsulating the core, in which the thickness of the outer layer if from 0.001 mm to 1 cm. A stabilized composition is prepared from an organic material to be stabilized and the resin masterbatch composition. A process for producing the resin masterbatch composition includes co-extruding in tubular form a core material encapsulated by an outer layer, wherein the core material comprises at least one additive, and the outer layer comprises a polymer, to form a filled tube; passing the filled tube into a sealing device that cuts the filled tube into multiple discrete segments seals and simultaneously seals each end of each discrete segment, thereby forming closed end pellets; and cooling the closed end pellets.

Encapsulated stabilizer compositions

Granular stabilizer compositions including concentrated blends of one or more polymer additive, and one or more co-active agent, which compositions are low-dusting and substantially free of a carrier polymer resin are disclosed herein, along with process for making the stabilizer compositions, and uses of such stabilizer compositions for providing enhanced protection of polymer resins against deleterious effects from air (oxygen), residual catalyst, mechanical stress, heat, and light.

Granular stabilizer compositions for use in polymer resins and methods of making same

Aqueous dispersions of cationic water-soluble polymers are provided, as well as processes for making and methods of using the same.

Aqueous dispersions

Processes for spray drying water-soluble and water-swellable vinyl-addition polymer-containing dispersions, emulsions and microemulsions to obtain substantially dry water-soluble or water-swellable polymer particles, compositions of substantially dry water-soluble or water-swellable polymer particles, methods of agglomerating spray-dried polymer particles, and methods of using sprayed polymer particles and agglomerates in water-treating, mining, paper, food processing, soil conditioning, solution thickening, biotechnological, and oil recovery applications are disclosed.

Aqueous dispersions of cationic water-soluble polymers are provided, as well as processes for making and methods of using the same. The cationic polymers contain anionic recurring units in amounts that encourage the formation of the aqueous dispersion and/or advantageously reduce the bulk viscosity of the aqueous dispersion.

Mannich (alk)acrylamide microparticles are produced at high solids contents without a significant increase in bulk viscosity by inverse microemulsion polymerization and provide superior dewatering characteristics.
