High molecular weight copolymers of maleic anhydride and methyl vinyl ether |
| abstract |
A process of manufacturing powdered copolymers of maleic anhydride with methyl vinyl ether in a mole ratio of 1:1 and a specific viscosity in a range from 2 to 5 by copolymerization of maleic anhydride with methyl vinyl ether in the presence of radical initiators to initiate polymerization. The process includes mixing maleic anhydride with an excess of about 3 to about 20 mol methyl vinyl ether per mol maleic anhydride and initiating a polymerization reaction with a radical initiator added in a quantity of from about 0.001 to about 1 weight % with respect to the maleic anhydride. The polymerization reaction takes place in the absence of other solvents. |
