Abstract

A limited coalescence method of making polymer particles having an average particle size of 3 .mu.m or less comprising dispersing the polymer particles in an organic liquid diluent after they are separated from the aqueous suspension medium in which they are prepared, to thereby eliminate or substantially avoid agglomeration between the polymer particles upon drying.
