Способ осуществляют путем полимеризации олефинов в низкокипящем суспендирующем агенте, в особенности в пропане, и при отводе реакционного тепла путем охлаждения за счет конденсации пара в присутствии металлоценового катализатора получают полиолефиновые воски; при этом предотвращается образование отложения на стенках при охлаждении реактора.The method is carried out by polymerizing olefins in a low boiling suspending agent, in particular propane, and when the reaction heat is removed by cooling due to steam condensation in the presence of a metallocene catalyst, polyolefin waxes are obtained; this prevents the formation of deposits on the walls during cooling of the reactor.
