Abstract
The invention provides polymer particles useful in a variety of applications, including coating applications such as packaging coatings. The polymer particles preferably have a volume-averaged particle size of less than 40 microns, more preferably less than 20 microns. In preferred embodiments, the polymer particles are precipitated particles, more preferably precipitated polyester particles, which are optionally free of low-molecular weight surfactant.
