Abstract
1,3-Bis[(1-alkoxycarbonyl-2-vinylcyclopropane-1-yl)carboxy]benzenes 1 [RO: CH3O (a), C2H5O (b)] were synthesized by the esterification of the corresponding 1-alkoxycarbonyl-2-vinylcyclopropane-1-carboxylic acids with resorcinol. The structure of the new vinylcyclopropanes was confirmed by elemental analysis and infrared (IR), 1H nuclear magnetic resonance (1H-NMR), and 13C nuclear magnetic resonance (13C-NMR) spectroscopy. The radical polymerization of difunctional 2-vinyl-cyclopropanes in bulk with 2,2′-azoisobutyronitrile (AIBN) results in hard, transparent, crosslinked polymers. During the bulk polymerization of the crystalline bis[(1-methoxycarbonyl-2-vinylcyclopropane-1-yl)carboxy]benzene 1a, an expansion in volume of about 1% took place. The radical solution polymerization of 1a resulted in a soluble polymer with pendant 2-vinylcyclopropane groups. © 1999 John Wiley & Sons, Inc. J Appl Polym Sci 72: 1775–1782, 1999
