Triazolinediones as monomers for polymer synthesis and polymer modification
- Univ. of Florida, Gainsville, FL (United States)
Triazolinediones are exceptionally strong electron acceptors, and are among the most powerful dienophiles and enophiles known. Reaction occurs rapidly with alkenes, vinyl ethers and esters, styrenes and B-diketones to yield a variety of novel copolymers. Recently, these powerful electron acceptors have been shown to undergo uncatalyzed electrophilic aromatic substitution with electron-rich aromatic compounds, for example, N,N-dimethyl aniline, 1,3,5-trimethoxybenzene, and n-methylpyrrole. Appropriately substituted monomers and/or polymers when treated with triazolinedions lead to a variety of novel polymers. These reactions also lend themselves to modification of preformed polymers, as well as copolymers. Polydienes are readily modified with triazolinediones to orderly change the hydrophobic-hydrophilic balance in the polymer over the entire spectrum. The relationship of the reactions of triazolinediones with electron donors to the problem of alternating copolymerization is apparent. The major emphasis of this paper will be placed on qualitative and quantitative comparisons between these two systems.
