ABSTRACT:
Amorphous copolymer of fluoromonomer, such as tetrafluoroethylene, with vinyl ester, such as vinyl acetate, having a substantially uniform composition is made by aqueous dispersion polymerization by maintaining essentially constant the proportion of the fluoromonomer and vinyl ester copolymerizing with one another. In one embodiment, this proportion consistency is obtained by reducing the agitation rate of the aqueous polymerization medium during the copolymerization reaction at constant fluoromonomer feed pressure within the polymerization reactor.
