Abstract
A new approach to the preparation of colorless and high transparent methacr ylic resins was described. N-Alkyl methacrylamide, the alkyl substituent of which was methyl, cyclohexyl, or isobornyl, was employed to copolymerize w ith methyl methacrylate, giving the copolymer with enhanced glass transitio n temperature around 10-15 degreesC higher than that of homo-poly(methyl me thacrylate). The comonomers, N-cyclohexyl methacrylamide and N-isobornyl me thacrylamide, were prepared by reaction of methacrylonitrile with cyclohexe ne and camphene, respectively. All the three kinds of copolymers showed the water absorption similar to that of homo-poly(methyl methacrylate) after t he samples were immersed in water for 2-8 days. The copolymers also showed high weather resistance toward sunshine in atmosphere for 16 months. (C) 20 01 John Wiley & Sons, Inc.
