Polymere Brenzcatechin-Derivate, 3. Darstellung und Eigenschaften von 3,4-Methylendioxybenzyl-methacrylat und seinen polymeren Derivaten

3,4-Methylenedioxybenzyl methacrylate ( 3 ) was synthesized from 3,4-methylenedioxybenzyl alcohol ( 2 ) and methacryloyl chloride. 3 was radically polymerized with tributylborane and copolymerized in cyclohexanone at room temperature under nitrogen. The following monomer reactivity ratios were determined M₁ = 3 : r₁ = 0,68 and r₂ = 0,40 for M₂ = styrene, r₁ = 0,78 and r₂ = 0,16 for M₂ = acrylonitril, and r₁ = 0,28 and r₂ = 1,47 for methyl methacrylate. Polymeric derivatives having 3,4-dihydroxybenzyl units in the side chains were prepared from homo- and copolymers of 3 . The thermal stability and redox behaviour of these polymers were investigated.
