Procedure

In 1 liter of methylene chloride was dissolved 92.4 g of 1-cyclohexylcyclopentanol. To the solution below −20° C., 74.3 g of acrylic chloride was added dropwise over 10 minutes. To the reaction mixture, 1.0 g of 4-(N,N-dimethylamino)pyridine was added and then, 125.0 g of triethylamine was added dropwise over one hour and below −20° C. This reaction mixture was agitated for 15 hours at room temperature and subjected to conventional post-treatment, obtaining an oily substance. Vacuum distillation yielded 110.5 g of 1-cyclohexylcyclopentyl acrylate (designated Monomer 1). The yield was 90.5%. Boiling point: 83-85° C./53.3 Pa
