GPC calibration for poly(methyl acrylate)

Summary Electrophylic vinyl reagents can be reacted with a protonated tertiary amine supported by a polymeric chain. We determined the mechanism of this addition in the case of vinyl methyl ketone and poly (4 vinyl pyridinium bromide). The first step is the addition of the vinyl compound on the tertiary amine, then protonation of the intermediate species occurs. The velocity constant at 268 K is 0.087 1. mole^–1. mn^–1 and the activation energy is 10 kcal.mole^–1.
