Abstract: The polymer having a repeating unit of formula (I) is prepared by condensation reacting aromatic dihalogen compound (A) of formula (II) and aromatic diol (B) of formula (III) in the presence of alkali metal salt at 140-250 deg.C for 1-12 hr. In formulae, Ar is phenylene, biphenylene, etc., X is chlorine and M is alkali metal, compound (A) is 4-fluoro-4'-(4-fluorobenzoyl phenyloxy)diphenylsulfone and compound (B) is selected from 2,2-bis- (4-hydroxyphenyl)propane, hydroquinone or 4,4'-biphenol. The alkali metal salt is potassium carbonate and its addition amount is 1.0-20 wt.% w.r.t. aromatic diol.

Abstract: The acrylic acid alkali metal salt resin is prepd. by steps: (A) polymerising acrylic acid and acrylic acid alkali metal salt in presence of crosslinking agent and radical polymerising initiator in alicyclic hydrocarbon org. solvent; (B) after-polymerising the carboxyl gp. of the obtd. polymer with water soluble diglycidyl ether; (C) adding low molecular water soluble polymer selected from polyehylene glycol or hydroxyethyl cellulose. The sametimely crosslinking agent is selected from diacrylate, triacrylate, polyethyleneglycol di(meth)acrylate or alkylenebisacryl amide of polyol having more two polymerisable functional gp.. The solvent contains 3-6 HLB surfactant and 8-15 HLB surfactant.
