| 摘要 |
The present invention includes: (i) a method for making a coated particulate comprising the steps of heating until liquid a polyolefin wax; fluidizing with a hot gas, additive particles selected from the group comprising an antioxidant, a processing stabilizer, an acid acceptor, and mixtures thereof; spraying the liquid polyolefin wax on the heated fluidized additive particles; and maintaining the fluidized additive particles at a temperature which is sufficient to prevent the formation of fibers and adequate to form discrete substantially coated additive particles; (ii) a coated particulate made by the above process; and (iii) a process for providing in-reactor stabilization of a polyolefin during a polymerization reaction, using the coated additives prepared by the above described method.
