Copolymers of ethylene with 10 to 98 percent by weight of conventional comonomers are made by copolymerization in aqueous dispersion, at least a part of the heat of polymerization being removed by evaporation of the ethylene. The vapors are cooled by a cooling medium by heat exchange, in a cooling z...

Beschreibung
Zusammenfassung:	Copolymers of ethylene with 10 to 98 percent by weight of conventional comonomers are made by copolymerization in aqueous dispersion, at least a part of the heat of polymerization being removed by evaporation of the ethylene. The vapors are cooled by a cooling medium by heat exchange, in a cooling zone situated above the polymerization vessel and communicating with the latter, the hot vapors being fed to the upper end of the cooling zone, the cooled vapors returning to the polymerization vessel, so that the vapors are cooled by the cooling medium while they are flowing downward.
