Study of radical copolymerization of aminomethylated derivatives of alkenylphenols with styrene

Aminomethylated derivatives 2-propenyl-, 2-allyl-, and 4-isopropenylphenols are studied as comonomers in free-radical copolymerization with styrene in bulk. As evidenced by NMR studies, in o -aminomethyl derivatives of alkenylphenols, stable intramolecular hydrogen bonds form between nitrogen atom o...

Description
Summary:Aminomethylated derivatives 2-propenyl-, 2-allyl-, and 4-isopropenylphenols are studied as comonomers in free-radical copolymerization with styrene in bulk. As evidenced by NMR studies, in o -aminomethyl derivatives of alkenylphenols, stable intramolecular hydrogen bonds form between nitrogen atom of the aminomethyl fragment and hydrogen atom of the hydroxyl group; these bonds are not destroyed up to 80°C Therefore, these compounds may be involved in free-radical copolymerization with styrene in which the inhibiting effect of OH groups is avoided at a temperature of 60°C. The values of r 1 and r 2 are determined for two pairs of comonomers: 6-morpholinomethyl-2-propenylphenol and styrene ( r 1 = 0.20 ± 0.01 and r 2 = 2.40 ± 0.04) and 2-allyl-6-morpholinomethylphenol and styrene ( r 1 = 0.090 ± 0.009 and r 2 = 2.40 ± 0.04).
