실험 절차

In 200 ml of methyl ethyl ketone were dissolved 19.4 g of maleic anhydride and 20.6 g of styrene, and to the solution was added 0.65 g of azobisisobutylnitrile(AIBN). The resulting mixture was heated at 60° C. for 2 hours under nitrogen atmosphere for performing polymerization. The reaction solution was then dropwise added to 500 ml of ethyl ether under stirring to precipitate a polymer. Thus precipitated polymer was collected by filtration and purified by repeating twice the THF dissolution-ethyl ether precipitation procedure described in Example 1. Thus purified polymer was dried under vacuum at 100° C. for 24 hours to give 31.5 g of a maleic anhydride-styrene copolymer. It was confirmed by elementary analysis that the copolymerization ratio was approximately 1:1. Mn was 55,400.
