N. Moszner et al., Polymerisation of cyclic monomers, 8 - Synthesis and radical polymerisation of hybrid 2-vinylcyclopropanes, MACRO RAPID, 20(1), 1999, pp. 33-35
Hybrid 2-vinylcyclopropanes were synthesised by the esterification of 1-met
hoxycarbonyl-2- vinylcyclopropane-1-carboxylic acid with hydroxy group cont
aining (meth)acrylates in the presence of 1,3- dicyclohexylcarbodiimide (DC
C). The structure of the new hybrid monomers was confirmed by elemental ana
lysis, IR, H-1 NMR and C-13 NMR spectroscopy. The radical polymerisation of
the hybrid monomers in bulk with 2,2'-azoisobutyronitrile (AIBN) results i
n transparent cross-linked polymers, whereas solution polymerisation partia
lly results in soluble polymers with pendant 2-vinylcyclopropyl groups.
