ABSTRACT:
A process to produce a free flowing fine polymer powder is provided. The process comprises the steps of: providing a polymer cement comprising a polymer either melt or dissolved in a solvent to form a polymer cement; dispersing an antiblocking agent within a stream consisting of steam to form atomization steam; atomizing the polymer cement; contacting the atomized polymer cement with the atomization steam; and recovering polymeric particles. Polymeric particles so prepared have an average particle size of between 100 and 1000 microns. In a preferred embodiment, the polymers produced are rubbery polymers which are free flowing.
