PETROL-FREE MALEIC ACID ANHYDRIDE / VINYLETHER POLEMERE. |
| abstract |
A process for the manufacture of benzene-free maleic anhydride/lower alkyl vinyl ether polymer having a specific viscosity ranging from about 1.0 to about 5.5 by premixing maleic anhydride and the alkyl vinyl ether in a mole ratio of between about 1:1.1 and about 1:2 in a cosolvent mixture of lower alkyl substituted benzene, a C6-8 alkane, a saturated lower alkyl ether with a lower alkyl vinyl ether as cosolvent and reacting the monomeric complexed mixture at elevated temperature and pressure in continuous contact with a peroxide initiator wherein the specific viscosity is controlled by adjusting the amount of lower alkyl vinyl ether in the cosolvent mixture. The polymeric product is recovered from the resulting slurry by vacuum drying. |
