Acetic Anhydride → HCID 15055049, compound

Participants

Reaction Steps

The poly(N-(4-tert-butyloxycarbonyloxyphenyl) maleimide is synthesized according to the following scheme. Di-t-butylpyrocarbonate is reacted with p-aminophenol to give p-(t-butyloxycarbonyloxy) aniline, I. Reaction of I with maleic anhydride then affords N-(p-t-butyloxycarbonyloxyphenyl)maleamic acid, II. Monomer II is modified by treatment with sodium acetate and acetic anhydride to yield monomer III, N-(p-t-butyloxycarbonyloxyphenyl)maleimide. Monomer III is polymerized in the presence of azoisobutylnitrile (AIBN) to yield poly-N-(4-tert-butyloxycarbonyloxyphenyl) maleimide.
