Method for controlled free radical polymerization or copolymerization of ethylene under high pressure in the presence of an initiator-controller

   
   

The present invention relates to a process for the radical polymerization or copolymerization of ethylene under high pressure in the presence of at least one polymerization initiating-controlling compound capable of providing, by decomposition under the polymerization or copolymerization conditions: at least one initiating free radical (Z) which carries at least one site for initiating the (co)polymerization; and at least one stable free radical (SFR) which carries at least one site exhibiting the stable radical state and which is stable under the polymerization conditions, with, in total, as many initiating sites as sites exhibiting the stable radical state.

Присытствыющий вымысел относит к процессу для радикальных полимерности или copolymerization этилена под high pressure in the presence of по крайней мере одна полимерность начинать-kontroliru4 составное способное обеспечивать, разложением под условиями полимерности или copolymerization: по крайней мере один начиная свободный радикаль (Z) носит по крайней мере одно место для начинать (co)polymerization; и по крайней мере один стабилизированный свободный радикаль (SFR) носят по крайней мере одно место exhibiting стабилизированное радикальное положение и стабилизирован под условиями полимерности, с, в итоге, так много начинать места как места exhibiting стабилизированное радикальное положение.
