    • Disclosed is a process for producing a carboxylic acid chloride by reacting phosgene with a carboxylic acid or an anhydride thereof, which comprises effecting the reaction in the presence of a homopolymer or copolymer of a monomer represented by formula (I) or (II) below, a copolymer of the monomers represented by formulae (I) and (II) below, or a copolymer of at least one monomer selected from the group sensisting of the monomers represented by formulae (I) and (II) below with another monomer copolymerizable therewith:CH.sub.2 .dbd.CHNR.sup.1 COR.sup.2 (I)CH.sub.2 .dbd.CR.sup.3 CONR.sup.4 R.sup.5 (II).In these formulae R.sup.1, R.sup.2, and R.sup.4 each represents an alkyl group containing from 1 to 3 carbon atoms, or an alkylene group containing from 3 to 5 carbon atoms provided that R.sup.1 with R.sup.2, and R.sup.4 with R.sup.5 may each combine to form a ring structure through >N--CO-- or >N-- in the molecule; R.sup.3 and R.sup.5 each represents a hydrogen atom or an alkyl group containing from 1 to 3 carbon atoms; and the alkyl groups and alkylene groups may have substituents which are inactive under the polymerization and chlorination reaction conditions.
