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.-

摘要： The preparation of poly(arylene ether ketones) by Friedel-Crafts polymerization, in the presence of a Lewis acid catalyst and a diluent, is conducted under conditions in which the polymer and/or its complex with the catalyst is suspended in the diluent during at least part of the polyreac- tion mixture if desired. The dispersant may be a polymer or an organic compound containing at least eight carbon atoms and is preferably a Lewis base. The dispersant preferably contains at least one molecular segment substantially compatible with the poly(arylene ether ketone) or its complex with the Lewis acid and substantially incompatible with the diluent and at least one molecular segment substantially compatible with the diluent and substantially incompatible with the poly(arylene ether ketone) or its complex with the Lewis acid.
