Abstract
The interaction of α-chloromaleic anhydride (ClMAn) and allylcyclohexane (ACH) was studied. These monomers were found to make a charge-transfer (CT) complex at a 1 : 1 ratio. Copolymerization of ClMAn and ACH in solution gave a white powder in about 50% yield of which analytical data suggested that ClMAn and ACH are copolymerized in a 1 : 1 ratio. By heating the copolymer at 190°C for 1 h under reduced pressure, dehydrochlorination occurred quantitatively to generate a double bond in the polymer chain at the position of maleic anhydride moiety. The dehydrochlorinated copolymer was found to make a CT complex with acetone but the value of the formation constant was smaller than that of monomeric maleic anhydride.
