摘要： A method of preparing a poly(arylene ether ketone) by a Friedel-Crafts polymerisation wherein a gelled reaction mixture is produced, comprising the steps of:
permitting the reaction mixture to polymerise in a first reactor until substantial partial polymerisation has occurred, but before substantial gelation of the reaction mixture;
transferring the partially polymerised reaction mix­ture into a second reactor having a nozzle at one end thereof and a piston;
permitting polymerisation to continue in the second reactor until a gelled, polymerised reaction mixture containing polymer of the desired molecular weight has been obtained;
discharging the gelled, polymerised reaction mixture from the second reactor through the nozzle by moving the piston in the second reactor; and
recovering and purifying the polymer.
