Procedure
A solution of 9.8 g of maleic anhydride (0.1 mole) and 11.2 g of 1-octene (0.1 mole) in 30 g of propylene glycol methyl ether acetate was heated under agitation and nitrogen to 95° C. A solution of 2 g of t-butyl peroxy-2-ethylhexanoate in 6 g of propylene glycol methyl ether acetate was then injected into the reaction vessel within half hour via a syringe pump. The reactants were agitated for another 2 hours at 95° C. before being cooled to room temperature. The product was then poured into methanol which caused precipitation of a white solid which was filtered and air-dried to give 12.7 g of a maleic acid/1-octene copolymer having a number 2 0 average molecular weight by vapor phase osmometry (VPO) of 2800. The approximate composition of the copolymer by 13CNMR:
