ABSTRACT:
Particles of ethylene-vinyl ester interpolymer containing at least about 30% by weight of copolymerized vinyl ester which are produced in aqueous dispersion media when recovered from such media exhibit a tendency to coalesce into unmanageable agglomerates which is prevented herein by adding an anti-coalescing amount of a lower saturated aliphatic monohydroxyl alcohol such as ethanol or isopropanol to the dispersion media and recovering the interpolymer particles therein in the alcohol-wet condition.
