ABSTRACT:
Polymer powders comprising aggregated polymer particles, said powders having a low content of fines and being suitable as processing aids in the manufacture of polyvinyl chloride, are made by spray drying an aqueous dispersion (latex) of two emulsion polymers, one of which has a dynamic glass transition temperature above 90.degree. C. and the other of which has a dynamic glass transition below 105.degree. C., the latter being at least 10 K. degrees below the former.
