Studies on the synthesis and reactivity of butyl glycidyl fum a rate
The reaction of epichlorohydrin (EPI) with potassium salts of butyl maleateand butyl fumarate was studied and the optimum conditions at which butylglycidyl esters are formed in high yield were established. It was found that partial isomerization of the product occurs in reactions involving the butylmaleate salt. Neat butyl glycidyl fumarate (FBG), however, is formed inreactions involving the fumaric acid derivative. The reactivity of the products obtained was tested in radical homopolymerization and copolymerization with styrene (ST), acrylonitrile and isobutylene. Thorough studies of the copolymerization of FBG (monomer F) with ST (monomer S) at 65°C showed that reaction can be satisfactorily described by means of the classic Mayo-Lewis model considering the reactivity of the terminal monomeric unit. The reactivity ratios rf and rs and the standard deviation Syvalues determined according to that model were equal to 0.0249, 0.1919 and 0.135, respectively. The approximate values of the Q and e parameters for FBG were equal to 0.8 and 1.5, respectively.
