Toluene → HCID 86738184, compound

Participants

Reaction Steps

A mixture of 98 parts of maleic anhydride, 112 parts of octene-1, 4 parts of azobisisobutyronitrile and 400 parts of toluene was reacted in an autoclave under an atmosphere of nitrogen for 8 hours at 70°-75° C. with stirring. After completion of the reaction, the reaction system was cooled to room temperature and 500 parts of cold methanol was added to precipitate a polymer, which was separated by filtration, collected and dried to obtain 140 parts of an octene-1-maleic anhydride copolymer (mol ratio 1:1, MW = 4300). A mixture of 105 parts of the so obtained copolymer and 400 parts of a 10% aqueous sodium hydroxide solution was reacted with stirring to obtain an aqueous solution of a water-soluble octene-1-sodium maleate copolymer (hereinafter referred to as water-soluble salt (II-5) or Na salt of (C8 -MA) copolymer).
