As far as I know, emulsion polymerization of vinyl acetate is usually done at temperatures lower than 80 oC (say 50-65 oC). While a temperature drop may occur at the start, when polymerization proceeds the chemists will detect a rise in temperature until it levels off & a steady state occurs.

Please see this PhD thesis entitled: "The Emulsion Polymerization of Vinyl Acetate"

https://ses.library.usyd.edu.au/bitstream/2123/381/3/adt-NU1999.0006whole.pdf

I think the above thesis which my students consulted is a very good reference.
