COATED POLYMERIC PARTICLES HAVING IMPROVED ANTI-BLOCK CHARACTERISTICS,METHOD OF MAKING SUCH PARTICLES, AND APPARATUS THEREFOR |
摘要 |
To provide superior anti-agglomeration, or tackiness-reducing, properties, o ne aspect of the invention is directed to coated polymeric particles, with each of the coated particles comprised of a polymeric substrate particle and a block-reducing coating on the surface of the substrate particle. The coating includes polymeric coating particles which advantageously may be in the form of a micro-fine powder. Also disclosed herein is a process for applying the polymeric coating particles onto the polymeric substrate particles, as well as equipment which is especially useful in producing the coated polymeric particles.
