Production of polymaleic acid |
摘要 |
A polymer or copolymer of maleic acid is produced by neutralizing (I) maleic acid in an aqueous medium with (III) an alkali metal hydroxide or ammonia at a molar ratio of (I) to (III) in the range of 100:0 to 100:90, polymerizing (I) with a polymerization initiator, adding (III) a further amount of the alkali metal hydroxide or ammonia at a molar ratio of (I) to (III) in the range of 100:100 to 100:130 in total through the previous addition and this addition and continuing the polymerization to the complete effect.
