Azobisisobutyronitrile → HCID 86738184, compound

Participants

Reaction Steps

A mixture of 98 parts of maleic anhydride, 112 parts of octene-1, 4 parts azobisisobutyronitrile and 400 parts of toluene was reacted for 8 hours at 70°-75° C. with stirring in an autoclave in an atmosphere of nitrogen. After completion of the reaction, the reaction mixture was cooled and then precipitated from 500 parts of methanol, followed by filtration and drying to yield 140 parts of a white powdery octene-1-maleic anhydride copolymer (mole ratio substantially 1:1; MW = 4300). A mixture of 105 parts of the so obtained copolymer and 400 parts of a 10% aqueous solution of sodium hydroxide was then treated as in Example 1 to obtain an aqueous solution of an octene-1-maleic acid sodium salt copolymer (mole ratio substantially 1:1) [hereinafter referred to as Copolymer (6)].
