Abstract
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.
